Airline reviews

Pros: "Good crew on this leg. While not always the case, they left the lights off for the entire flight and only had them dimly on when doing their final checks. It was also nice that everybody was handed water bottles that wanted one."
Cons: "Alaska Airlines doesn't have seatback screens and only limited beverage selections on these shuttle flights."

Pros: "Crew was very nice"
Cons: "The seats are so uncomfortable"

Cons: "Still no tablets for movie viewing. I get that you have an app.. but I sure miss the bigger than my phone screen tablets to watch on."

Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"

Cons: "Seat cushions are too thin."

Pros: "Checking bags was harder then it should have ate setvices was below par. But boarding was good crew was polite, and vary receptive to requests."
Cons: "New bag limitations"

Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."

Pros: "I didnt die."
Cons: "That they fed me cookies all day. Better tasting water. Variety of free snacks."

Cons: "Employees who just don't care"

Pros: "The efficient boarding. Unlike other airlines, overhead compartment is large enough so passengers don’t need to check in at the gate."

Pros: "Management as well as staff nice...First trip with Alaska and made my trip nice .. Got a good deal price too."
Cons: "Nothing."

Pros: "Plane very warm, not comfortable. Only one pass for beverage service."
Cons: "Very warm air vents did not work."

Cons: "45 minute delay due to fog"

Pros: "Friendly staf. comfortable seats. And no charging for checknig my bags."

Pros: "on time"
Cons: "I have never been on a flight where I was bumped in the leg or arm repeatedly. Passengers were constantly up and down the aisle along with the carts hawking their wares. I trussed myself up like a turkey with the seatbelt so I wasn't on the armrest so as not to get hit again. My grandson who is a lot smaller than I, tried to put his head down to sleep on the tray table. He looked so uncomfortable. I know the deal is butts in the seats, but even the seat bottom is horribly uncomfortable. These planes have become cattle buses. I put up with it because there is no choice and I can't afford first class."

Pros: "On time."

Cons: "Na"

Pros: "How friendly and professional"

Pros: "Able to text ..."

Pros: "Newer aircraft"
Cons: "1-1/2 hours delay, no reason was given."

Pros: "Ditto statements above"

Pros: "Love the tablet rentals... staff were super friendly..."
Cons: "Kid friendly choose on purchasing food items!! Kids are not going to eat brie or Gouda cheese"

Pros: "good"

Cons: "Nicest people ever."

Pros: "My favorite airline to travel from Denver to Puerto Rico, round trip, and in Atlanta I will make the stopover, I also feel so safer to travel with my cat ... they are the best airline in everything"
Cons: "Let people who travel with pets earn extra points for taking them with Delta"

Pros: "The accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."

Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

Cons: "Nothing all excellent"

Cons: "It was great! Nice job Delta !"

Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"

Pros: "Christina brown was amazing at gate"

Cons: "The main economy seats were far too narrow."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"

Cons: "No meal option and my video screen volume did not work"

Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"

Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""

Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"

Pros: "Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines."
Cons: "Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA."

Pros: "Everything was fine. Delta did a great job."
Cons: "The kid screaming in my ear for 3 hours"

Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."

Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."

Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

Cons: "Cabin was too hot!!!!"

Cons: "Cramped seating for premium Econ"

Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

Pros: "Crew was very helpful."
Cons: "On the way to Minneapolis the plane was BEYOND PACKED. There was no room for even my backpack."

Pros: "In a pinch they were able t"

Pros: "Was able to sleep for once. Nobody in center seat."
Cons: "Crying babies"

Pros: "Everything was perfect !! Staff friendly"

Pros: "Great in every way"

Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

Cons: "Check in lines were crazy long"

Pros: "Gate personal kept us notified about flight delay. Flight crew was very positive on plane and they were as miserable about the delay as we were. Snacks and drinks were brought out. The gate crew keeping us updated is what saved the name of Delta. If she didnt do that people would have been angry."
Cons: "Flight was supposed to depart at 0730. Actual departure was 1045. Three out of seven of the flight crew were not happy about how badly they were being treated by call center and /or management while they were delayed with us at gate. Snacks were brought out because of delay but they were just junk food. Nothing I could eat due to allergies."

Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"

Pros: "The entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."

Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

Pros: "really helpful and friendly service and nice seats."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."

Cons: "Excellent service excellent pilot"

Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."

Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"

Pros: "The flight got us from Anchorage to Atlanta on time."
Cons: "No A/C vent controls for each seat. No reading light for seats. No flight attendant call light buttons were accessible. NO WiFI or video entertainment. Coach plus seats were just like the rest of coach, just in front of them. Seats would not adequately recline. The plane was still PACKED."

Cons: "long wait and delayed flight"

Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"

Pros: "We have been flying Delta more often lately. Great service, newer planes in and out of Alaska, and affordable first class tickets. Snack basket had chocolate bars..."
Cons: "Short 3 hour flight-no complaints"

Pros: "Entertainment. Center was great"
Cons: "Boarding has been made so complicated it's a joke."

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "nice snack"

Pros: "Crew was great."
Cons: "turbulence"

Pros: "1st class flight attendant sat through the entire flight (except for offering drinks and food early in flight). There were passengers NOT wearing masks through the flight but she wouldn't know that since she never left her seat"

Cons: "Me probably. You guys were excellent!"

Pros: "Nothing"
Cons: "Not allowed unleashed dogs to take my seat or be in my flight"

Cons: "The plane had a mechanical issue that they needed to address (due to the fact that they prior crew did not address it) and we sat in the gate for 2 hours waiting. No worries water was offered by crew and the flight had no food."

Cons: "Flight got delayed. We paid for assigned seating for our almost 85 yo mom. And the change in flight no one asked for to get seated in the front of plane. Instead she was seated all the way in the back. It was physically exhausting for her."

Pros: "Crew was great"
Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."

Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."

Pros: "Crew was nice"
Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."

Pros: "Overhead bins were newly done with plenty of space since carryon can be placed vertical on side. Decide holder built into the seat was very nice."

Pros: "Nice staff"

Pros: "Pleasent"

Pros: "Pretty standard flight"
Cons: "Inconvenient timing and overcrowded with obnoxious children sitting on laps. No attempts made to change their behavior by crew or parents."

Pros: "Spacious"
Cons: "Ran out of food that I like"

Cons: "The WiFi did not work and so no entertainment for a flight of almost 4 hours."

Cons: "I hate Americans boarding process"

Cons: "3+ hour flight with no TV/ entertainment"

Pros: "Not using kayak."
Cons: "Worst flights in history. It took three days to get from Italy to the US. Do not use kayak!"

Pros: "They got us there quickly."

Pros: "Ahead of schedule"

Pros: "Seats were too tight and too close together."

Pros: "Movie and tv selection was good. Boarding was a cinch, we took off exactly on time, seats were comfortable, too."
Cons: "Airline misplaced my boyfriend's checked back with our duty free Portuguese wine in it. It still hasn't been delivered to him the next day. They had three hours to get the bag on the flight."

Pros: "Nothing in particular"
Cons: "Outlet did not work"

Cons: "Flight crew was late and didn’t try and make things move faster to make up time. Kept saying they wanted to go Puerto Rico and that’s where they should have been going."

Pros: "Same"
Cons: "Same"

Cons: "Food"

Cons: "Everything. Had to sleep overnight in airport and was late coming home."

Pros: "Wonderful, again. Will fly American any chance I get!"

Pros: "The onboard entertainment selection was excellent; great movie selection, wifi connection, and flight details. A winner! So much so that I chose to binge watch movies and not sleep!!"

Cons: "No tvs!!"

Cons: "the new seats are awful"

Pros: "Tv and power outlets"
Cons: "This one attendant didn't get her name but was very cold to me"

Cons: "Long delay"

Pros: "Crew"
Cons: "Small plane"

Pros: "Good serice,"
Cons: "Good service to switch flight pattern from greenville to new bern but still a delay that cause a 2 flight connection. Lots of on-line issues with check-in, overall a stressful day, hopefully it will all work out!"

Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."

Pros: "Everything"

Pros: "The plane was sleek and clean. I had a good amount of room even in coach!"

Pros: "Nothing. AA is the worst airline. Period."
Cons: "Rude flight attendants, delayed flight (as always), just AWFUL."

Cons: "The flight was 3 hrs late, of which 1.5 before boarding, and almost 1.5 stuck in the plane."

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

Cons: "Seats too small and the gentleman next to me was a big guy so crowded over into my seat some."

Pros: "Very friendly staff"

Pros: "The plane was new on the interior and comfortable."

Cons: "The customer service from AA representitives in the airport was completely unnacceptable and the absolute worst service I have recieved in an airport to date! One incident during this trip was as follows: When arriving in Charlotte and running to catch my connecting flight, I arrived as the lady at the desk was closing the door, she looked at me and rolled her eyes. When I went up to the desk along with the other passengers arriving from the same flight as me the AA representative said "Hurry up , I want to go home!! At a point I'm just going to cut you off and that will be it!" She was of no help to me in anyway amd was forced tonstay the night in charlotte ; Normally this would not have been such a big deal, However I am on emergency leave from the Navy rushing home because I have a very serious family emergency, that representitive was very lucky I held my temper! From now on thanks to the poor unproffessional customer service I received I will no longer be flying American Airlines!"

Pros: "Yes"

Pros: "Fast and friendly"

Pros: "Good job"

Pros: "Very helpful assistance staff, food and drinks delicious, excellent service onboard"
Cons: "At Denver assistance hadn’t been arranged"

Cons: "Only bathroom on the plane was closed due to issues. Plane was cold and cramped."

Pros: "Nothing"
Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag. What is baffling is that when I arrived at Denver people were getting complementary check in baggage. I’m so dissatisfied with the booking and the amount it has now cost me ruining any savings I’d had for sanfrancisco"

Cons: "Delays in flights were a disappointment"

Cons: "Missed connection due to mechanical"

Cons: "Crowded planes."

Pros: "Everything was very nice."

Pros: "Everything was on time and all the staff were professional and friendly"

Pros: "The variety of movies"

Pros: "The crew was friendly"
Cons: "The seats are small, no real space, things over all looked run down, feels like I’m taking a city bus but even those have more room."

Pros: "Nothing unusual every was smooth"
Cons: "Not applicable"

Pros: "Nothing"
Cons: "Everything"

Pros: "Staff was nice!"
Cons: "I didn't like the luggage restrictions associated with our tickets."

Pros: "Curtial personnel"
Cons: "Late departures both ways."

Pros: "It was generally quiet and peaceful. I called the stewards at one point and they were very prompt and attentive."
Cons: "Teeny tiny seats on an overnight flight? I had to ask my rowmates to clear the row so I could find my glasses that had fallen under my seat because there simply wasn't room to maneuver even an arm down to manually search for them. This is not to mention that most people sleep on these flights; how is that comfortable for most regular Americans?"

Pros: "Suitcase arrived at the carrousel on time , much better than Houston."

Pros: "United payed for the room and 20 bucks for food."
Cons: "Late. Missed the connection to Gillette and had to stay overnight."

Pros: "no delays!"

Pros: "I ended up missing my connecting flight because the flight left the airport almost an hr late....once i get to my connecting flight...ive missed it...soooo i had yo wait 4hrs for the next available flight & missed my doctors visit......im sooo pissed....."
Cons: "Missing my connecting flight"

Pros: "Boarded on time. That is all."
Cons: "After boarding, we waited on the plane for a long time before they said there was a mechanical problem and we would need to deboard while they fix it. After waiting another four hours they finally canceled the flight. They couldn't get us another flight and said to come back the next day to see if there is another flight out."

Cons: "I was not told that if I voluntarily checked my carry on bag I wouldn't be able to make flight changes later."

Pros: "Plane was on time"
Cons: "I am 5'4" and had no leg room. My knees touched the seat in front of me the whole time. The in seat entertainment was broken on the entire plane for the flight. Simply won't ever fly in a plane so cramped ever again."

Pros: "Flight was great."
Cons: "Only negative was that the seat was cramped, not much room."

Cons: "Unreliable wifi."

Pros: "Getting off the plane"
Cons: "Bathrooms weren't working, huge lines in aisle, lackluster service. Overhead bins were full by Group 3. late takeoff."

Pros: "Needed to get to a hurting friend asap who's husband was dying. When I checked my luggage the delta employee gave me a heartfelt hug & words of encouragement Which meant more to me then anything. That's not in any training manual that's the heart of a great employee...."

Pros: "Once on the aircraft everything was just fine"
Cons: "First of all it was delayed, no big deal but once i checked in I wasn't even assigned a seat. I try to find an agent at the boarding gate and none to be found. They finally arrive 30 min before take off and then assign me a middle seat when I specifically picked my seat weeks earlier and of course was one of the last people to board barely enough time to search for a place for my bag and get to my middle seat in the back of the aircraft. Not even a sorry or any type of compensation for a terrible experience"

Pros: "New plane"
Cons: "The way you bord the plane"

Pros: "On time."
Cons: "United has squeezed its Economy class customers into seats that are tolerable only for the shortest. If I were an inch or so taller, I would have found the space intolerable. As it was, my knees were against the seat in front. For a flight as long as this one (over 5 hours from Anchorage to Denver), it was uncomfortable to say the least. The middle of the plane was nearly empty, because United charges $75 per seat for an upgrade. For the round-trip for two of us, that would have added $300 to our bill. The fact that so few are willing to pay the upgrade fee indicates that the increment is too large."

Cons: "There was a lot of empty seats but the crew never offer the guy seating next to us to move. His elbow kept hitting the buttons and turned on the tv screen while I was trying to sleep. I saw he went to ask one of the crew but was told to wait until flight takes off then no one helped him after. Flight was bumpy most of the time..not a very happy customer"

Cons: "Didn't receive my carry-on when arrived in ELP. Finally got it the next day."

Pros: "Everything went smoothly"

Pros: "Nothing"

Pros: "Quick boarding"

Pros: "I made it to my destination"
