Loved Alaska. We had an issue with late baggage being boarded and scheduled maintenance so we were a bit delayed from pushback. The crew was sympathetic as it was the start of forth of July weekend. They offered complimentary wine. Very sweet.

Everything was fine except that both times I used the bathrooms, they were really a mess and when I politely mentioned it to a flight attended, she was pretty rude about it and didn't clean it up.

Cons: "First class in an airplane this size is a bit limited (especially legroom) when in the first row."
Pros: "yes"
Cons: "Not on time."
Pros: "Upgrade to premium was amazing. Crew was perfect"
Pros: "Baggage drop and checkin was a breeze"
Pros: "The crew was accommodating during the long delays boarding and deplaning:"
Cons: "Delays were extremely long to the destination and upon arrival no gate was available for our plane which caused another long delay."
Cons: "$400 flight and they only offered orange juice and water. Cheap cheap cheap!"
Pros: "Everything was smooth"
Cons: "Courteous and servient steward!"
Pros: "Great crew, a lot of space in the aircraft"
Cons: "More entertainment"
Cons: "Seats and the seating arrangements were poor. Seats were assigned at different places even if you are part of the same family/ticket. The aircraft do not have 3-4-3 seat arrangements. So it would be difficult for families with 2 kids."
Cons: "Really old plane. Not well cleaned. Bring sanitary wipes for seat and tray tables. But cabin crew is top notch."
Pros: "The crew was excellent and boarding was a cinch. I volunteered to check in my girlfriend and I's bags and the process was very easy."
Cons: "Compared to other airlines, I think their food and beverage service was a little lacking."
Pros: "I love the new plane interiors and love how you wrote about the features in the in-flight magazine. I’m a designer and it was so nice to read about why you developed those features. Love the lighting. Bravo!"
Pros: "Sfo is ridiculous... we sat on the tarmac for an hour waiting for a shuttle bus"
Pros: "Crew was great"
Cons: "It was tight at the gert"
Cons: "Delays"
Cons: "The flight was delayed 6 hours. The snacks I wanted were unavailable. When we finally landed we were taken off the plane in the back of the airport down stairs attached to the plane and loaded onto a bus and taken to the airport underground. Worst experience ever."
Pros: "The staff were pleasant"
Cons: "The flight was late."
Pros: "Early Arrival"
Cons: "Bathrooms were not maintained during duration of flight. With airlines like Delta and JetBlue stepping up their in-flight service Alaska needs to get with the program. I think everyone and their mothers we're in boarding group C but yet no one was in A...make it more dispersed."
Pros: "Nothing"
Cons: "Alaska airlines is a consistent let down. This was the LAST time I will ever fly them. A 9 hour delay because their captain called out 1 hour before the flight. They did NOTHING to compensate the entire plane, made ppl leave back into a city with their bags, no food, etc. The gate agents handling it could've cared less and told people to call and complain it wasnt their problem. The service was horrible from top to bottom and cost people their entire day. Many missedevents, connecting flights and Alaska all the while didnt even comp a coffee to people theyd stranded from 6am to 6pm ,"
Pros: "Flight crew was wonderful."
Cons: "They ran out of cups......"
Pros: "Very faster arrived."
Cons: "No meals."
Pros: "Crews and service are nice"
Cons: "Flight was an hour late."
Pros: "Movies"
Cons: "lack of Cleanliness, one crew member was rude and pushy (not to me but in her tone and to others),"
Pros: "Friendly crew, clean plane"
Cons: "Go go Wi-Fi was terrible...spotty service for about 20 minutes, but ultimately the crew just shut off the Wi-Fi. Ran out of food 1 hour into the 5 hour flight. were they not expecting a full flight?"
Pros: "Flight from Newark to SanFran was smooth, and entertainment options were great!"
Cons: "Crew wasn’t overly welcoming (though certainly not rude at all), and boarding was rushed at the gate just to stand in huge line waiting to get on aircraft."
Pros: "Crew was very good and respectful. The pilot constantly kept informing us of flight route and possible changes. Even made the passengers aware of an amazing light storm outside the aircraft that was impressive sight to see."
Cons: "The seat I sat in felt as though I was slipping off of it. i was constantly having to reposition and get comfortable. My lone issue."
Pros: "On time, not bumpy, new chocolate snack, clean, easy boarding -- you did it all!"
Cons: "Flying."
Pros: "Liked the seats. Liked the service. The food on my previous flight HX60 was better."
Cons: "Flight was delayed. Other than that, nothing to complain about. Like I said, ordinary flight."
Pros: "entertainment"
Cons: "gate change and no display text on digital display that the updated gate was indeed the flight to SFO"
Pros: "Entertainment ststem"
Cons: "Heat: service; lack of water/drinks; lack of soap in bathroom"
Cons: "Our flight was delayed while we waited for a crew member to fly in to cover for a FA that called in sick. Gate agents didn’t provide many updates while we waited. The were only 3 snack items for purchase available on the plane. Seat didn’t recline"
Pros: "Ummm...I bought a ticket on Alaskan and it ended up being a Virgin aircraft."
Cons: "There wasn’t a power outlet at my seat."
Pros: "I arrived - finally (though stuck on the runway at SFO as I write this)"
Cons: "Crowded, chaotic boarding area & process at Boston Logan. Checked in seats manually since systems apparently down. An hour delayed (on takeoff) for no apparent reason and delayed waiting for gate on arrival. Seems to happen regularly with Alaska but not JetBlue Broken restroom - should have at the very least let coach customers use First Class restroom rather than get by with one Broken wifi - none the entire flight Limited food which ran out quickly Flight attendants trying but seem harried and confused and not very attentive"
Pros: "Everything was great! This was my first time flying Alaska Air and I could not have had a better trip! Everything ran according to schedule, I was comfortable during the flight, slept the entire time, staff was great!"
Cons: "The woman making announcements did not specifically announce the duration of the flight as we were departing. I was able to figure it out on the map option on the screen, but I would've liked to hear it verbally. Only suggestion I would have is an announcement on the plane for which baggage claim belt our luggage would come out of. I may not have heard it though, if there was an announcement. It was not difficult at all to figure out once I was in the baggage claim area, however if this was known while we were still on the flight, I prefer to know this info!"
Pros: "Nice movies Comfortable seats"
Cons: "Noisy air con Seat not reclining Headphone jack not working No storage space"
Pros: "Flew Alaska air - Plenty of leg room and much more than any qantas domestic flight! Empty flight and very short."
Cons: "Flight was delayed. Inflight entertaining streaming system was not working. Too many people insist on not checking their luggage under, so we almost didn’t have space for our carry on by the time we were allowed to board."
Pros: "Flight said canceled but they rerouted it to Oakland but no where on any monitors does it say this. The screen for boarding said Cancun even while boarding to Oakland. No one helping people when they got off the plane to transport them to SFO. Standing in the rain waiting for shuttle.Poor experience"
Pros: "Friendly flight crew"
Cons: "I like complimentary food and entertainment"
Cons: "Wasn’t given the opportunity to choose my seat and was put in last row."
Pros: "We love flying Alaska Airlines. Staff was very helpful. Lots of leg room. And we arrived ahead of schedule."
Cons: "Our original flight had to be re scheduled and we arrived later than planned but it all worked out well."
Pros: "That we were in the air"
Cons: "That I waited 3.5 hours bc of a delay when I could have been with loved ones not stressing about my flight. Also, how long it took to notify customers. I love Alaska Airlines, but it's the little things that set you apart. Don't lose them!"
Cons: "Economy is always cramped, not just an Alaska comment. My computer almost got destroyed because the guy in front leaned his seat back"
Cons: "My emotional therapy dog of 7 pounds got part of her paw ripped off on an airport escalator. Though she was bleeding profusely all over me, I was not allowed to use the first aid kit to bandage her. I had to bring her to an emergency vet upon landing in Minneapolis"
Cons: "By the time I boarded I was unable to take my bag on as all overhead compartment space was gone. My bag was not prioritized, instead I had to wait FOREVER at SFO for the bag to arrive. There were over 6 flights assigned to the same baggage carousel. I think since we have to pay now for bags to be checked, I should have been compensated for NOT being able to take my bag onboard and for being forced to wait a very long time to retrieve it...exactly what I had hoped to avoid by carrying on."
Pros: "Nothing"
Cons: "I felt like cattle flying on flight 308 sea-sf. Obese intoxicated guy taking up 1/2 my middle seat that I paid $200 for. Pilot said we were 16 on take off line. I think he is being sarcastic - I hope he is. Not a pleasant experience at all. 34 min late & no wifi. 30 min to get to gate. BS"

Outstanding service from Sonya and Ariella!

TV screen not working

my row of TVs didn't work

Cons: "the flight was 2 hours delayed but the staff continuously kept us up to date"
Cons: "It was a 6 hour flight and I didn’t know only 2 snacks and a water were available on the plane until I got to the airport. Almost everything was still closed at the airport. We were quite hungry and thirsty."
Pros: "It has been over 2 years and I still remember the service, comfort and atmosphere of this flight. Whatever JetBlue is doing, it works!"
Pros: "I liked the male flight attendants on my flight. They were nice and cheery and was always willing to help. The inflight entertainment and WiFi was great. The snacks were also good."
Cons: "I forgot to the flight attendant’s name but she was quite rude. I traveled with an infant who required warming up of her milk in a bottle and I would ask for hot water and she failed to bring it over. I requested hot water twice. Initially when the plane was taking off- she stated she cannot bring anything while the flight was taking off but even after take off and in cruising altitudes she did not come over until we rang the call bell and another flight attendant came over. Second time mid flight we happen to ask the same flight attendant for hot water as she passed by— she nodded her head but again never returned with the hot water. Again I hit the call button and another attendant came over and gave me water. I felt that she did not like attending to the flight guests and always seemed to give an attitude. I understand traveling with a child may be hard for others, but imagine the parents who have to care for a starving baby. The flight was also a bit too warm."
Pros: "Basic flight"
Cons: "Major delays. Poor updates on app regarding timeliness."
Pros: "Crew was very friendly and responsive"
Cons: "Would’ve been nice if they offer headphones. Maybe they did and I just didn’t notice."
Pros: "Very good service"
Cons: "More food choices"
Pros: "A 6+ hour flight is always tedious but jet Blue is always the best option, with live tv and a good supply of movies and snacks."
Cons: "Quicker departure, 20 minutes on the tarmac, but that’s not the airline fault...FAA Boston"
Pros: "Crew was nice and accommodating. Plenty of leg room in regular cabin. Good entertainment options.?"
Pros: "Great crew. Mint experience is fantastic, actually great airline food. Better than any other domestic first class. Free internet!"
Pros: "crew were great. free snacks with lots of variety. Great assortment of films available."
Cons: "Flight was significantly delayed with no real clarity when the final departure time would be."
Pros: "-Excellent crew -Nice leg space even if Economy -Free DirecTV -Free internet with decent speed -Electric outlet under every seat -Free seat selection at the time of booking"
Cons: "-Boarding process: should organize the boarding area so that lines can form for each boarding group"
Pros: "Not too full of a flight"
Cons: "It was delayed 3 hours"
Pros: "Boarding process was smooth, and attendants were kind and entertainment system seemed good."
Cons: "Attendants could allow passengers to use extra leg room seats if they are empty once in the air. Would be great if the default setting for the screens was OFF."
Pros: "Crew was great. Snacks were abundant. R"
Cons: "Ran out of pineapple juice and giving out earplugs would be nice"
Pros: "Friendly crew. Extra snacks and drinks were a big plus on a long flight."
Cons: "There were not enough people that checked their carryons, which lead to a long delay in boarding. Jetblue people should have demanded more checked bags to avoid a long delay in boarding. The flight was painfully long due to snow, which is understandable."
Pros: "I like the comfort of the flight and the kindness of the crew"
Cons: "I'm disappointed that my carry-on has been charged like a suitcase, that has stolen time to reach my booked house in the city"
Pros: "It was really nice having a USB charger under every seat."
Cons: "Our flight was delayed by 2 hours and I was only notified when I had arrived at the airport."
Pros: "The crew are always nice and the plane clean."
Cons: "We always have a comfy aisle seat but it has happened on occasion by the time we are seated there is no room in the overhead not just for our luggage but people in our row. I would think an aisle seat is a premium seat. I think they allow people on with more than one carry on so people in other rows use our overhead bin."
Pros: "In-flight entertainment was excellent: many options including in-flight wifi."
Cons: "I think it is time for US airline companies to provide complementary meals in their long flights. A 6 hours flight with just a small bag of chips? European airlines offer a complementary full meal even with a 2-hour flight..."
Pros: "Onboard staff was great"
Cons: "Boarded late, other flights planned on this trip one was canceled and the other was also late. Was told at boarding that bag checked at boarding would be at carousel at the end of flight, but it wasn't. Took forever to get a response and then the bag is still missing 2 days later and response has been terrible trying to sort it out."
Pros: "Seats were great. Excellent movie selection. Friendly flight crew."
Pros: "Comfortable seating, great movies, courteous service."
Pros: "Free WiFi, snacks and friendly staff"
Cons: "I had to gate check my carry on bag, which is one of my biggest traveling pet peeves."
Pros: "Really nice crew. Appreciate the snacks. The jetliner has great leg space. I love the DirectTV and movies."
Cons: "Nothing."
Cons: "2 hour delay. Too full and not enough over-head space for carry-ons, forcing some of us to check-in our carry-ons. Too many problems with the entertainment system (and downloading movies) for my seat and it resetting/initializing several times."
Cons: "Late take off and landing by 1 hour and sitting on tarmac forever upon arrival. JB used to be better"
Pros: "The flight attends did the best they could with information updates. They didn't know much more than we did."
Cons: "The catering issues delayed my flight almost 2 hours. Thank you to jetBlue for the email apology."
Pros: "Extremely slow taxi-ing at both Boston Logan and SFO led to delays. Plane was very cold which made it hard to sleep"
Cons: "Excellent flight attendants Clean, comfortable plane (other than the temperature)"
Pros: "Long flight so drinks and snacks were appreciated"
Cons: "The rude pushy passenger next to me who kept push8ng 8nto my space and stated that because I was on the Aisoe and he in the middle he should be able to push me 9verbbut that was not Jet Blue’s responsibility. Although the crew offered to move him to the back which he refused but it did quiet him temporarily."
Pros: "Good red wine Good movies"
Cons: "waiting to board, waiting after being boarded-- with more than one hour delay total"
Pros: "The airconditioning"
Cons: "The plane was delayed for hours"
Pros: "Leg room was good"
Cons: "Had issues with freezing monitors on way out and on way back"
Pros: "Crew members were lovely. Selection of tv shows and movies was very nice."
Cons: "Fairly long flight from East Coast to West Coast. I wish there had been a dinner option."
Cons: "Delayed"
Pros: "Staff was great-- welcoming, professional."
Cons: "My audio plugin didn't work, and I spent the trip pressing it in by hand."
Cons: "My seat wouldn't lean back irrespective of how hard I pushed it. It went half way back compared to the seats next to me and then it got stuck"
Cons: "Late departure; headphone jack on my armrest was faulty so I had to hold the plug in the whole time if I wanted to hear sound of movies; once we were at the gate in SFO, it took a good 10 minutes for them to open the door to let us off."
Pros: "I didn't like much of anything EXCEPT THE FREE WIFI. While it's nice to have all the bells and whistles (free in flight TV/movies, snacks/beverages, etc.), the basics need to be met too - which they weren't."
Cons: "I didn't like that the plane was delayed 1.5 hours for no good reason. Why have us sit on the plane in a cramped atmosphere instead of delaying it at the gate first until your ducks are in a row? Then the in-flight entertainment audio periodically cuts out, and they were resetting the TV system over 3 times. In addition, I had requested a price reduction when I booked the flight since JetBlue's website is buggy and the price went up $80 in front of my eyes while other people booked the seat I wanted, and they weren't willing to give me anything."
Cons: "The Jet Blue counter person was not helpful at all providing direction to us from International Terminal to Domestic terminal C. No help at all to passengers who are not familiar with Logan Airport. Major major disappointment!"
Cons: "Had to check basic backpack at the last minute because no overhead space. Unclear instructions as to where to pick it up on the SFO end, leading to further delays getting out of the airport. (Already landing close to 2am at the beginning of a work week - minutes count.)"
Pros: "Jet blue is ahead of the rest. Free WiFi, snacks, and drinks!"
Cons: "Entertainment hiccups meant that I wasn't able to listen to the radio."
Pros: "Direct TV offered excellent list of channels."
Cons: "Movie list is outdated."
Pros: "Enjoyed entertainment, service, comfort"
Cons: "The eating options where limited and unclear specially for such a long flight"
Pros: "The trip was comfortable and quiet"
Pros: "Arrived 45 minutes early!"
Cons: "None"
Pros: "Delayed"
Cons: "Top carrier"
Pros: "The crew was great. The pilots too."
Cons: "The audio and video at my seat did not work correctly."
Cons: "The flight attendants were fantastic!"
Pros: "Well organized and easy to check in."
Cons: "No"
Pros: "this is the airline"
Pros: "Excellent crew and clean aircraft"
Pros: "Crew was amazing. Pilots were attentive to kids and answered questions. Everyone was very welcoming and helpful."
Cons: "They didn't have some of their food options (and they apologized for that up front), but then ran out of the others by the time they got half way through the plane. That was tough for a five hour flight that went through dinner time."
Cons: "Wonderful"
Pros: "Very comfortable, no complaints."
Pros: "Good entertainment options."
Cons: "Only water and coffee available. Flight had been delayed over an hour."
Cons: "Crew didn’t serve drinks/snacks; otherwise nice and short flight"
Cons: "No delays. And have the terminal bridge in working order"
Pros: "Crew was friendly"
Cons: "An hour and a half late, terrible communication about scheduling"
Pros: "Good flight in air"
Pros: "Yes"
Cons: "Took off late. Other than that very comfortable and great experience"
Pros: "The seat get’s bit hard after 14 hours."
Cons: "The food was ok but not great"
Pros: "Smooth flight."
Cons: "Tight seat. Small space."
Pros: "I really enjoyed the service on Delta. The entire process was better than what i've come to expect on airlines. My flight attendant was Kate, and she was awesome - super friendly, professional, thoughtful."
Pros: "Overall service was great."
Cons: "Flight was delayed 5 hours."
Pros: "Having three seats."
Cons: "I had three seats to myself! After getting elbowed all the way from Amsterdam to Minneapolis, I was tired and I slept three good hours."
Pros: "Great service"
Cons: "Look, if your kid is so young that he can’t get in a plane without screaming for four hours, you shouldn’t bring him on a plane and subject 200 people to that. It’s rude and selfish."
Cons: "Sat on the runway for over an hour to get the gate. Unacceptable."
Cons: "I understand Mother Nature causes issues tkayakhat no one can control but when I'm receiving updates from the 3rd party travel app that isn't the airline before receiving any information directly from the airline via the gate agent or Deltas travel app and the gate agent not being able to verify the 3rd party travel app something is wrong."
Cons: "Delays, delays, delays... first class ticket from BOS to MSP got me a 6 hour delay and a middle seat in econ main cabin at the back of the plane. Delta you suck!"
Pros: "Got to London on-time (early, actually) and safely. The in flight meal was okay. The leg room in comfort plus was great, the mobile app was awesome, and the staff (check-in, gate, cabin and flight deck) were professional and friendly all around."
Cons: "The leg room was great, but as a broad-shouldered guy, the width of the seat was miserable. Unfortunately, the Delta 767 doesn't offer any upgrade for a wider seat beyond Delta One, and my employer won't spring for that. Too bad there isn't a premium economy option. Also, the entertainment unit in the seat next to mine malfunctioned, which you wouldn't think would impact me that much except that because it was "seeing" touches randomly throughout the flight, the screen would turn on, off, brighter, dimmer, play random stuff, and just generally be as annoying as possible to everyone nearby throughout an overnight flight."
Pros: "On time"
Cons: "Take a long time to taxi to the gate & getting off the plane."
Cons: "Tray table was broken, I was downgraded from Comfort plus to main cabin after a plane swap with no mention by anyone and no compensation. Flight was delayed 45 minutes because a flight attendant was running late and then to top it off, at the end of. The flight the attendants blocked anyone fromaim cabin from leaving until all of first class had departed, even when no one was coming they still Blocked it off. This is a practice I have never seen on delta and haven't seen in aviation in almost 20 years in the US"
Pros: "Plane was on time."
Cons: "My seat assignment was in the last row of the plan when the plane was not full"
Pros: "Leg room and seats are very tight and I'm a small person."
Cons: "Coach class is very crowded."
Pros: "Food was plenty."
Cons: "Long security lines at Logan. No free WiFi"
Pros: "on time, good food, good films enough space to sleep in economy."
Cons: "the stewardess only went up one side of the plane offering eye shades and when i asked for one she seemed really miffed."
Pros: "The movie selection is very good"
Cons: "Both boarding the flight and getting off the flight were severely delayed. The flight attendants also seemed to ignore half the plane when handing out drinks and when picking up trash. I had to flag someone down after they had simply walked past my row both times."
Cons: "Force me to take a bad seat"
Pros: "We were not happy with our flight my flight got cancelled 3 times I miss work they need to reimburse us and also reimburses the hotel cuz we had to stay at a hotel because they cancelled our flight three times and then our flight that we went out on Monday was late because of a flight attendant arriving late to the hotel to the airport"
Pros: "Delta flights run one time and their fleet seems newer than most with comfortable seating. Having free movies in the seat back ahead of you is a big plus with a good selection of movies. Snacks are good and crew is always friendly and accommodating. We fly almost exclusively with Delta for the aforementioned reasons."
Cons: "Boarding is a hassle no matter the airline with few exceptions. You would think someone could figure and efficient method to get people on the planes. I suppose it could be the public that is the problem. Not a problem with Delta they run a good airline."
Pros: "It got me to SFO earlyish"
Cons: "Was told to go away and wait for name to appear on screen for seat assignment. Was seated apart from travel companion. Got to sit next to folks with questionable hygiene, seat broken. Seatbelt broken. Stuck in back of plane window seat and was supposed to be “happy”. I was brilliantly ignored by crew. Seat back entertainment broken snd flight crew never answered the call button. Got to watch bag handlers throw and drop luggage like true gorillas. Delta, this time you truely are the worst. Wont book you again."
Cons: "Delay in leaving from the airport there were issues with Web checkin Crew wasnt able to give me my boarding pass for the connecting flight and kept saying going to the other counter"
Pros: "We'd paid extra for main cabin so hot to choose seats and got in flight entertainment.. Staff were friendly."
Cons: "No free wifi."
Pros: "I was thankful for the early boarding with a lap infant and was very pleased with the options for entertainment on the TV monitor."
Cons: "The main issue I had was that we sat in row 34 and the noise from the engines often made it difficult to hear announcements, even with headphones in. Look into possibly zoning the audio and turning it up a click or two for rows behind the engines."
Cons: "My wife was told she could not board our flight from Boston to Paris because her passport was expired, even though it was not expired. We were told that in Europe passports cannot expire within 3 months of your departure. However, Delta never let us know about this rule until we literally were boarding the plane. How they could not make us aware of this until we were boarding the airplane is unbelievable and unacceptable. This has ruined our vacation which has been in planning for the last six months."
Cons: "Zero communication to the passengers as to why we were delayed for almost an hour sitting on the plane"
Pros: "They arrived on schedule."
Cons: "Seated in the rear middle seat. I had no options to select a seat when I checked in or made my reservation that wasn't an extra charge. I'mover 6' tall and middle seats are painful, especially cross country. Airlines need to be a little more attentive to their customers' needs. If a passenger is taller than average, and the flight is more than 60 minutes, provide comfortable seating at no extra charge. If a customer has a short layover, which their system knows about since it is the sourve of the flight plans, put the customer toward the front of the aircraft since these flights are habitually late and customers end up having to sprint through airports to try to make connections."
Cons: "Jet airways sucks"
Pros: "The only flight that was a bit better was from Mumbai to Hyderabad."
Cons: "Almost the entire trip, due to the following reasons: 1. The online check in process didn't work at all. The Delta staff at the Boston airport weren't pleasant and courteous at all. 2. Poor coordination between Delta & Jet Airways - the meal preference was selected before flight at the Jet Airways website but the same didn't get registered properly, even though the website confirmed to me that it was all set. This resulted in appropriate food not being available to the customer on the flight from Boston to Amsterdam. The customer had to literally starve on the flight. 3. The pursers and stewards on the flight from Boston to Amsterdam weren't pleasant and courteous at all. For anything they were asked, their responses ."
Pros: "It only took them 10 minutes to turn things around to make up time for the delay."
Cons: "The seat pockets were not cleaned."
Pros: "Delta service and conford are great."
Cons: "Pay for wifi"
Pros: "you must be kidding me!!! nothing to say good about this fly !!The sad part I'm American Express Delta SkyMiles credit card holder and they couldn't do anything for meThe only good thing we arrive in Mexico"
Cons: "flying to Mexico with. my two boys !!to begin I have to call Delta to put us seat together because the time of the fight had changed!! before we are siting by de middle of the plain when a booked r three seat together !! but than i got a imail confimatin with separete seattle for the kids!!we end up sitting all the way back on the plan!! we end up sitting all the way back on the plane l!! no TVs no windows in the last sits by the only two bathrooms on the plane with two boys that was not fun at all !!The sad part I'm American Express Delta SkyMiles credit card holder and they couldn't do anything for me when I called them"
Pros: "Delta always has a nice professional crew. We were served within a reasonable time and I felt comfortable the whole flight."
Cons: "The pressure is the cabin with really bothering me. I've flown several times and never had the pressure to bother me but it was really hurting my head."
Cons: "No pre flight service in first class even though we sat at the gate for an extra 30 minutes."
Pros: "Seats were comfortable"
Cons: "Provide coffee at least"
Pros: "Crew was OK"
Cons: "Seat was uncomfortable. There was no power outlet."
Pros: "I didn’t like anything at all"
Cons: "They have to add electronic devices or charge plug on it"
Pros: "Seats were pretty comfortable. We were allowed to deplane down a staircase off the back of the plane. Very cool."
Cons: "N/A"
Cons: "Baggage claim number was wrong. They almost took my bag away"
Pros: "The seats were decent for a domestic flight. Everything was timely."
Cons: "More food. Better entertainment."
Cons: "PHX airport baggage claim was a mess. I had to wait 40 min to pick up the luggages."
Pros: "The crew was great, efficient and professional."
Cons: "My tv was broken and only played maximum volume."
Pros: "Plane was clean"
Cons: "My belongings stolen"
Pros: "Coffee"
Cons: "Only snacks available at 5am"
Pros: "Quick boarding"
Cons: "Very cold."
Pros: "Entertainment system was up to date with personal screens."
Cons: "Flight was delayed by an hour. The new departure time was moved twice after we were already invited for boarding. Attendants failed to communicate new times or make any announcements absolutely whatsoever. Just stood in line to board for almost an hour."
Pros: "Flight crew were very apologetic"
Cons: "Missed connecting flight from Miami. Only one flight per day. Had to take a flight to an alternative location, drive for an hour down the coast and take a ferry to my final destination."
Pros: "Nothing"
Cons: "Was missed due to delayed flight"
Cons: "The flight was delayed. The food was not great. There is not a lot of space in these planes, and it was a long flight. There is no power supply."
Cons: "Entertainment system went down toward the beginning of the flight. The crew seemed irritable, but that was probably because people were upset about the entertainment system. We had to listen to a loooong speech about their credit card. I, personally, don’t like sales pitches over the intercom in the middle of a flight. Had the movies been working, it would’ve paused during the long speech. Not cool at all!"
Cons: "Aircraft at least in our section was very cold the whole flight. My young son was very cold even in a sweatshirt. I was very cold in a sweater, shirt, and jeans. I asked a crew member if they might have a blanket to cover my son, he brusquely replied “No blankets, no pillows!” So we just froze for 5.5 hours."
Cons: "headphone jack defective but more importantly the SFO arrival gate not available for over 45 minutes...."
Pros: "Flight attendants actually seemed to care about what they were doing. Seats were pretty comfy for once."
Cons: "Flight delayed with no explanation or apologies. Putting two and two together from the airport monitors it looks like they had to swap planes due to a scheduling or maintenance issue. Just another chapter in the neverending saga of delayed American airlines flights"
Cons: "No message to call with passengers with kids to board first or any military personnel boarding first."
Pros: "Generally clean plane with good entertainment system and technology overall. Diabetic meal much better than in the past."
Cons: "Didn't announce meal choices at the start so flight attendant had to repeat herself every. Single. Row. They forgot my diabetic meal on the last part them forgot to include cutlery and it took a long time to sort out but they were otherwise lovely."
Pros: "Nice flight, great leg room, staff was friendly and flight was on time."
Cons: "Not having boarding passes for the entire trip and not checking luggage thru to Charlotte was a hassle."
Pros: "Friendly attendants, plenty of coffee. Great service."
Pros: "Due to a strong tailwind we arrived 45 minutes ahead of schedule. Great service with attentive attendants. However the plane was older than me, no real entertainment system or outlets to plug in smart devices."
Cons: "Plane needs to be retired or retrofitted to accommodate smart device charging."
Pros: "The flight to Washington was fine. It was the flight back that I have issues with."
Cons: "My issue with flying back American is that...I didn't. They boarded us on the plane, moved down the tarmac, and then checked to see that we had a brake problem. They took our plane out of service (which I get, I would want brakes before takeoff), but then they never updated us on our status, until I physically went to the counter to ask an hour later. This is when they informed me that the flight was cancelled and we were rebooked on the 9pm flight (Mind you, this is 12:30p and I have a 2 year old with me). Luckily, I was able to book JetBlue and get home earlier (8:00pm)"
Pros: "We had to wait in the airplane upon arrival in La Guardia NY because wheelchair was not ready."
Pros: "Friendly crew"
Cons: "No entertainment."
Pros: "Flight was on time."
Cons: "The plane was dirty, the window had a leak, the TV was too far away and the sound system to watch the movie was broken. When the plane is in that poor of a condition, it's time to replace it. F."
Pros: "The flight crew was professional, friendly and competent. They served the dinner as early in the flight as possible."
Cons: "This was a plane with central screens along the aisle, and the airline chose to broadcast a sci-fi action movie with almost constant flashing blue light, and violent action scenes. This was first of all a movie that many people, including me, would never choose to watch, but since it was on the aisle screens there was no getting away from it. It was also unsuitable for children, even without sound. But mainly, I object to the showing of any film in that situation - only aisle screens available, and on a night flight where most of the passengers are trying to sleep. I was awakened several times by the flashing lights. Other things: one of the bathrooms was not very clean, and the plane felt like the usual cattlecar, with just 3 seats on each side of the aisle, which is unusual and unpleasant for a transatlantic flight."
Cons: "For a flight five hours or more I was disappointed that there was no complimentary food. It otherwise it was fine"
Pros: "blanket made it comfortable"
Cons: "No entertainment options"
Pros: "I really enjoyed the movies on this flight and they had us change to better seats before we took off"
Pros: "See above"
Cons: "See above"
Cons: "Surprisingly, AA provided the worst experience of the overall itinerary, compared to Aer Lingus and Iberia. The AA plane was outdated, cramped legroom - despite having purchased an "upgraded seat" and departed 1hr late"
Pros: "Was on time"
Pros: "We arrived safe."
Cons: "The plane had been on the ground for 6 hours prior boarding time, yet we leave until 1 hour late. Waited for the food to be loaded and then waited for paperwork to be signed. Really?"
Cons: "People still using mobiles as we were taking off. Crew seemed not too bothered."
Pros: "Old school seat. No foot rest. Small plane to go coast to coast."
Cons: "UI on the entertainment system was horrible."
Pros: "The flight was on time and the crew are nice with the people"
Cons: "Too crowded not able to take my other luggage on board."
Cons: "Jetway should not be backed up all the way to the counter. Stop calling so many groups for boarding without knowing that no one is actually getting onboard. Force subsequent groups to step aside until called."
Pros: "Good experience all around."
Cons: "15 minutes late. No big deal though"
Pros: "Things went ok"
Cons: "The plane was old"
Pros: "Crew was nice including those helping with boarding."
Cons: "Difficult to recline chair. Limited snack options. Landing was a bit rough."
Pros: "This leg of the trip was not packed. There was an empty seat between me and the person next to me"
Cons: "This flight was 6 hours. It did not have frontal entertainment, which was not pleasant. They did not offer blankets. The plane was cold as I boarded the plane. I asked for a blanket and was advised they didn't have any. I was so cold the entire flight that I still have a cold due to the flight. I froze the entire flight. I stuffed my arms in my shirt and let my hair down for warmth. Also, I learned my lesson. Pack my own blankie for comfort. I checked my carry on in Aruba due to overhead capacities. My bag had my sweatshirt and the blankie Delta bankie I acquired when I flew from SFO to ATL."
Pros: "I got to my destination safely. That's about the only good thing."
Cons: "The flight was delayed 4 times. The airline was not very helpful during times of delay - normally airlines would offer food or drink vouchers - none of that. The flight was delayed for a total of 4 hours. When I arrived into LAX, I had requested if I could go on an earlier flight if there was space (rather than catching the later one - an hour later). They asked me to pay $200 to change it. Fair enough if you want to charge me for a change of ticket - but then the plane that I was supposed to go on got delayed for 3 hours and you don't offer any sort of compensation - thats really not something I expect from American Airlines"
Pros: "Crew was friendly. Seats comfortable for economy. Routine pretzel/cookie/peanuts and beverage. The crew picks up the garbage almost immediately after giving it me...huh? Then I'm left holding it the remainder of the flight when the come back through again. Now for the kicker....I had two flights the same day so I opted to buy the All Day Pass for $25.95!!! What? It was a 2 hour flight each way... Can't they prorate for flight duration or something??!! I ended up watching 1 movie "Superman vs Batman" that was 1 of 4 options of movies that come with the $25.95 package. Other movies available are an additional $5.99 to "rent". Wow...ruined."
Cons: "See the pro section it won't let me copy and paste into the con section."
Pros: "Nothing"
Cons: "I'll never book AA again."
Pros: "The extra legroom for economy plus seats"
Cons: "The food was tiny and not good"
Cons: "They made us wait for a group of passengers who caused a 50-minute delay."
Pros: "No meals no entertainment no free internet"
Pros: "very friendly crew"
Cons: "the food"
Pros: "I found it appalling that on a 6 hour flight there were not only no complimentary alcoholic beverages, but that the price of a mini bottle of wine was $9!!!! Ridiculous."
Cons: "One complimentary alcoholic beverage."
Pros: "Th Roland was very good as was the entertainment from BOS to SFO, but may as good from SFO TO OGG. They plane was older smaller and the entertainment ability was lacking from SFO TO E"
Cons: "The maple crisps were excellent from BOS to SFO. The pretzels were boring from SFO to BOS."
Cons: "Still in Houston after spending the night. Flight from Boston to SFO WAS DELAYED SEVERAL TIMES and we would have missed our connection to HNL. So we were diverted to IAH, where we spent the night and will leave for HNL soon."
Pros: "Check in and bag check were easy and fast. Kiosk system works well. Excellent entertainment offerings!"
Cons: "I realize there is no real food service in coach, but a little variety in bagged snacks would be nice."
Pros: "We like to have our carry-on available under the seat so I thought I was planning ahead by getting the second row. Turns out the front row puts their carry-on under their seat and the second row gets screwed. All my extra leg room was lost with my bag taking up the space because it could not fit under the seat. They shouldn't charge extra money for that seat and I felt cheated."
Cons: "No space for carry-on under seat in second row for upgraded leg room seat."
Cons: "Really expensive internet"
Pros: "For an extremely late gate arrival, United personnel were very accommodating."
Cons: "One flight attendant was more than curt and impatient when taking food orders. Cabin announcement told passengers to check menu in setback pocket. There was no menu. Attendant didn't offer one until another passenger who overheard conversation requested menu. As a frequent United traveler BOS > SFO, normally a 5-6 hour flight, attendants always seem to be rushing, brusque."
Pros: "Boarding was as expected, flight was on time, all was OK. Nothing to recommend particularly. d"
Cons: "Few choices in beverages and food. No decaf or green tea or coffee except instant coffee. "Snack" was nothing much."
Pros: "A very tall, male, flight attendant very wonderfully took me almost all the way from one end of the horseshoe to the other. I didn't catch his name but he was SO helpful."
Cons: "My flight was delayed by a few minutes and by the time we got to San Francisco, boarding was almost done for my connecting flight. I had to literally run from one end of the United terminals to the other... the entire horse shoe."
Cons: "I told attendant my carry on had Med equipment. She proceeded to stow other larger carryons and tried to get me to check it — then she just put it in biz class. Cabin was hot. They brought me just after takeoff instas of at lunch time. My entertainment system didn’t work and the only response was “we’re aware of it” no attempt to fix, no apology. Then flight attendant skipped my tow with drinks."
Cons: "It was quite late"
Cons: "the boarding process is horrible and feels rude. The design of the united gates is horrible, the long lines block others walking by. The lack of enough overhead space for carryon's is obnoxious. Overall very disappointing."
Cons: "Flight was super delayed scheduled to leave at 6:30 left at almost 9. Small updates with not much information. Entertainment system not functioning. Had to get a tow to the gate after landing??"
Pros: "Entertainment free and plenty of choices"
Cons: "Not even any free snacks, seats do not recline much at all"
Cons: "I arrived at the airport only to find out that they had instituted a no carry on policy for basic economy and that I'd have to check my bag. They acknowledged that they had not informed me of this but that I'd still have to pay. The flight was delayed and the crew was extremely rude through out the flight, to top it off the in flight entertainment and wifi didn't work and the seat was incredibly uncomfortable"
Pros: "Staff was friendly"
Cons: "Wireless didn't work either way. Uncomfortable seats"
Cons: "WAs delayed for over 5 hours and missed my connecting flight. Had to abort takeoff go back to the gate and there were 2 issues with the plane"
Cons: "United sucks soooooo bad"
Pros: "I loved being in economy plus! The meal was a wonderful surprise and after my tv screen was reset, I enjoyed 2 movies. Nice staff and service."
Cons: "Having to go to the back of the plane for the bathroom."
Pros: "Full flight, we got on smoothly and took off on time. The plane was clean and the pilots during abbouncekents were easy to understand and funny."
Cons: "I had to wait over 1.5 hours to use the bathroom because of the food and drink carts. The flight attendant would not let me use first clsss and told me I had to wait. That was way to long to make someone wait."
Cons: "I did not fly from Boston to SF on United. I did not fly to or from Boston. Please fix your algorithm"
Pros: "Not much. Staff were reasonably pleasant. Boarding process is horrible."
Cons: "United is still flying ancient 757s. Broken tray tables, lights no working in the lavatory. Treating people like cattle with the 1,2,3,4 lanes is unpleasant and demeaning. Everything is getting cheaper and cheaper."
Pros: "Crew was great. Very friendly and accommodating ."
Cons: "When we landed we waited 30 minutes to get to our gate. There was nowhere for the plane to disinbark."
Pros: "New plane, great service."
Cons: "The hot meal was gross, but that's too be expected these days. It was nice to even get one, honestly. In flight wifi didn't work but the crew was great about helping us get in touch with customer service about it."
Cons: "Got re-seated into a non-recline, bulkhead exit row. For a tall guy like me that's a death sentence on a 6h flight that's delayed extra at the end of a day"
Pros: "Took off late but landed on time"
Cons: "Packed in like sardines. Hot on board."
Cons: "Wifi only allows certain number of passengers to connect. I couldn't connect entire flight along with many others."
Pros: "Friendly and gracious crew"
Cons: "Enterertainment Wi-Fi system went down with a few hours to go."
Cons: "1. Comfort: the headrest on these seats is so uncomfortable! It just props your head forward and causes a lot of neck strain. For most short haul flights, this is not a big deal, but it really makes for an unpleasant journey on the cross-country flights. Also, the four-seat middle section is so poorly designed. There is no way to store personal items under seats without invading the space of your neighbor because the metal frame supporting the row of seats doesn't match with the seats themselves. 2. Entertainment: United could not support continuous streaming of movies/TV shows for every passenger. My movie paused and froze so frequently that I gave up on finishing it and then felt like I had wasted my time. The speed and reliability reminded me of trying to watch movies on a dialup connection. It would be so much better to just have the TV screens built into the seats. All in all, United got a bad batch of planes and should try to take this into consideration when working with Boeing/Airbus on the next order."
Pros: "Flash for mac did not install"
Cons: "I felt like I was on my way to my death"
Pros: "It appeared as though I would miss my connecting flight and then crew moved me to an empty seat by the door so I could get off to make my flight!"
Cons: "The plane was too cold!"
Cons: "Crabby flight attendants"
Pros: "nothing"
Cons: "they have the worst customer service."
Cons: "No announcement of the proper Boarding numbers"
Pros: "Flight was stuck on the ground for 2 hrs because of a generator issue, so I missed my connection. The United app nicely pre-booked me on the next flight to my destination without my having to do anything, which was cool. Internet didn't work but they refunded my purchase."
Cons: "The legroom is so much worse than jetBlue (which I usually fly) I almost couldn't believe it. Because of the generator issue the flight ended up being almost 9 hours. They ran out of ALL FOOD for purchase except chips (which they didn't even offer for free despite everything), so those of us in the back of the aircraft had our choice of a bag of chips for $4, or no food for 9 hours. Also, I paid $20 for the internet for the entire flight but it only worked for the first hour so I couldn't do any work."
Cons: "Were held up by TSA in San Francisco because we were not given receipt for our dog who traveled with us. (We had a 2 hour layover in SF and took dog outside the security area for relief). Then the ticket counter in SF was understaffed and it took a long time to get the receipt printed (Once at the counter the agent was very helpful, efficient and quick). Should have a pet area inside the security of airports, like Palm Springs does."
Pros: "It was a comfy plane ride."
Cons: "I liked everything."
Pros: "Pleasant and attentive flight staff. Stewardess made a fresh pot of coffee and was back with a cup in less than five minutes. When a passenger got sick after take off the stewardesses handled the situation quickly and professionally."
Cons: "Nothing really"
Pros: "Boarding was consistent and timely"
Cons: "Older, worn interior, especially if seats are pushed back"
Pros: "On time boarding, nice crew."
Cons: "No free food, not a lot of options of free drinks"
Pros: "Attendants were friendly and helpful."
Cons: "One of the attendants was pushy and rude."
Cons: "My seat cushion was not in correctly and very uncomfortable. Movies were free on my last flight and coat money on this one."
Cons: "The first contact in the airport was quite rude when informing me that I had to measure my suitcase for size. I have carried this suitcase on on every airline for over 10 years....the size got smaller and United got $25.00....not happy. There was NO free movies, no access to TV, flight pattern....nothing and it could not be turned off. ONE cookie for a coast-to-coast flight. What happened to United?"
Pros: "We were bumped up to economy plus where there are outlets available. Outlets are nice. The entertainment options were very good."
Pros: "Old plane, no plugs, no in flight movie, didn't even offer complimentary snacks. Had to pay $10 for a snack box on a 6 hr flight. Completety unacceptable that on such a long trip, they offered no complimentary food, no movie, and although they offered "entertainment" on personal devices, you needed to download the united app to watch on your personal device. But wait, NO PLUGS??. So basically your phone / ipad battery will die 1/2 way through the flight and then you will have no way to use your phone after you arrive at your destination. Way to go united. Your corp execs should be ashamed for making you the worst airline with the highest prices."
Pros: "Flight from hell!! Delayed originally for one hour, then two hours air traffic control issues, then delayed three more hours due to engine trouble because of poor quality maintenance on the aircraft. Flight crew just went through the motions like automatons. What little food choices were available were terrible. Absolutely no leg room on flight. Should have used a bigger plane for a non stop transcontinental flight. I will NEVER fly United Airlines again!!!!"
