Pros: "The crew were very professional and friendly. The comfort of the seating was great as well."
Pros: "The new seats are great - outlets and usb ports that actually work and seats that are comfortable. While I like having the entertainment screens provided, since I had a nice device to watch films, it was very pleasant. A couple of good films were available."
Cons: "I don't understand why the people who get seats in the rear of the plane have to board last. Not only do they have the discomfort of waiting to get on the plane and sitting in the back, but there is no room for carry on luggage by the time they get on. It seems like a double whammy."
Pros: "Crew were are polite and had warm hospitality."
Pros: "Great crew, nice service, comfortable."
Cons: "Nothing. Loved it."
Pros: "Seat was good. Crew Service also was good"
Cons: "Food. Meal service. Coffee. Screens for movies"

Cons: "I was not notified that my card was declined and this caused a ton of delays"
Cons: "The plane was amazingly cramped."
Pros: "The crew were friendly, and the seating were uncomfortably hard. Seat pitch weren’t as great. Mood lighting were nice."
Cons: "More comfortable seat, offer a meal service since it is “transcontinental”."
Cons: "It is much better now"
Cons: "Could have been on time"
Pros: "Nothing"
Cons: "What have been nice if I was told that seat availability was nonexistent. I tried checking in each day without any information such as give it up you suck and you’re going to get the worst seed no better how much you try to avoid it…"
Cons: "The flight was oversold and my husband did not have a seat assignment. The desk agent was helpful and was able to put us together"
Pros: "Crew was friendly and fun. Seats were roomy with plenty of leg room."
Cons: "No soap in bathroom stall. Told crew who tried to correct it but it was broken. Boo..."
Pros: "Half of the flight was empty. I asked of I could move to the row behind. I was told that was premium seating and I didn’t pay for that. I didn’t appreciate being addressed like that. And did ot really matter when nonoe is sitting there or plenty of other seats."
Cons: "She could have just let me sit there. I should have been told that the seat didn’t recline when the ticket was pirchase."
Pros: "I always enjoy Alaska but this was another level. I was horribly late and still processing at security with 10mins until take off and the guy at the gate called me to see where I was - gave me mins to make it - which I did - just.. I was traveling to San Diego to meet my family for the weekend - I would’ve been in severe trouble had I missed the flight. Thanks Alaska!!"
Pros: "Seats were decently comfy. Good entertainment selection."
Cons: "Delayed almost 2 hours"
Pros: "We left on time and arrived early with a smooth landing"
Pros: "The crew was excellent. The entertainment was good."
Cons: "They changed our seats from the original ones. We ended up in the last seats. No way to recline. Very noisy."
Pros: "Would have been a great flight overall except...."
Cons: "Three flight attendants were socializing loudly to the point that it disrupted us from sleeping on an overnight flight. We had to ask THEM to keep it down. You’d think it would be the other way around on a red eye. Even after that they keep blabbering at the top of their voices! Surprised how inconsiderate they were. And yet, despite their gift of gab, they couldn’t make coherent announcements over the speaker. Food has two stars only because there was nothing to rate."
Pros: "I was so impressed with the genuine kindness and caring of the crew."
Pros: "Friendly staff"
Cons: "No food offered but I usually don’t eat food but some passengers were asking about the food service"
Cons: "Paid for and reserved a premium seat 6 weeks before flight but got reassigned to a non-premium seat upon check-in. I had to call customer care for a refund of the premium upgrade. No more live TV unlike the old Virgin America."
Cons: "They cancelled my 5:30 pm flight and text me that they put me on a 6a.m. flight the next morning without offering me a hotel or anything. I had to make new arrangements myself and the only option was to fly out earlier in the day and lose a day of sightseeing and time with family that I made the trip for in the first place. I had to race to the airport to get there in time. It ruined our trip."
Pros: "TSA pre-cleared me so I didn't even have to take off my shoes and there wad no one else in line in front of me. Alaska Airlines has comfortable seats with lots of leg room. We didn't get fed but there were many choices of movies and t.v. shows to watch."
Cons: "We sat on the runway for 45 minutes"
Pros: "Flight attendants were very nice and helpful."
Cons: "Our seats did not recline - this was a red-eye flight so not seats that do not recline is a problem. The plane was very cold and we kept our jackets on but it was still too cold. The flight attendant said it was warmer in the center of the plane. That's great for them but didn't help us since we were not seated in the middle."
Pros: "Crew was great, dealt with angry customers on delays well"
Cons: "The flight was delayed over an hour due to booking too many on the same gate. And late planes"
Cons: "If there was a less than one star that is what they deserve. SFO flight was late. They gave away my seat on my connection to Kalispell. They basically blamed me for being late and not being there on time. Two others from my flight were allowed to make the connection but told me that they gave my seat away because I was late. We all showed up at the same time from the late flight. I talked to 3 people including customer service and did not get a single “I’m Sorry”. Do they not communicate with each other when a flight is late and they have passengers for connections running late? They told me they don’t talk. The best they can do is put me standby for 9:30 flight and if I cannot get on that flight I have to wait until morning. My daughter is in a competition tomorrow morning and thanks to Alaska Airlines I’m going to miss it. I’m sitting here writing this review, paying for a dinner I should not be paying for and probably searching out a hotel room until morning when I can catch a flight. Unbelievable the lack of empathy."
Pros: "The mood lighting on the plane."
Cons: "Not applicable; everything about this flight was great!"
Pros: "The entertainment is great on Alaska."
Cons: "The flight got delayed a number of times, until it was 1:30 late. Then, since I have medical problems, and I was freezing (despite a sweater and a coat, I asked the flight attendant for a blanket and explained why, and she said flatly that there were no blankets on board. Just a terrible terrible red eye."
Pros: "Great attitude of crew. Very pleasant and attentive. Made the best of their way to take care of everything"
Cons: "Might want to look into refurbishment of the aircraft at some point soon. Lots of thing S worn out or not working"

Pros: "Real tray tables! A magazine! Power jacks!"
Cons: "Waiting for a gate agent so they could open the door in Seattle."
Cons: "Should announce to download Gogo entertainment app before we get on the plane!"
Cons: "1 hour delay. I asked. Front desk said it was due to sfo fog. Me: Isn't it 2017? They have radars now; I have flown from Boston under severe snow storms. Yes. I have."
Cons: "Waiting in front of the gate for one and a half our after the initial boarding time in uncertainty. If the flight is delayed please tell us in advance, not let us hover around the boarding gate waiting and waiting."
Pros: "Nice ppl and comfortable plane, great service all around"
Cons: "N/A"
Pros: "There was a huge delay due to weather. The plane didn't take off until almost 2am, however the crew kept everyone up to date and did everything they could. Upon arrival I had an apology email from Alaska with a discount, this amazed me as usually airlines don't offer you anything when the delay isn't "mechanical", and even then you usually have to complain. I felt this made Alaska's customer service memorable as they went above and beyond."
Cons: "The seats were small and cramped."
Pros: "The two flight attendants in the aft cabin were an absolute delight.They made the flight a great experience."
Cons: "The captain announced we would arrive early in Seattle and we were in fact late."

Pros: "There was actual room for my legs."

Pros: "Nice polite and helpful crew! Nice flight!"
Cons: "Only 1 snack and a beverage for a 5:30 hour flight"
Pros: "I liked the people around me! It’s telling what kind of customers show up to businesses we frequent. In this case, I’ve been deeply impressed with my fellow passengers on JetBlue. Teamwork makes the dream work, and your company makes it easy to arrive relaxed as well!"
Pros: "Nothing"
Cons: "Booked to travel with others and return flight itinerary was changed prior to our trip. Friends have to wait longer at airport and we now have to leave earlier. Outbound plane broke and we ended up leaving 3 hours late. Updates were poor and we were left wondering what was happening. Got to our destination at 3am. Given a $75 credit that can only be used for future tickets. Why not for baggage or seat upgrades? Not planning to fly this airline any time soon."
Cons: "Full flight... out of food for sale by row 18 ?!?!? WTF is that??? It happens every single time, and I travel JB 5+ times a year. Didn't hear a single announcement flight was boarding early (after extremely long delays). The Gate next to mine was shouting updates every 60 seconds."

Pros: "Movies for free"
Cons: "The one hour delay"
Pros: "JetBlue has comfy seats and is generous with snacks"
Cons: "Why on earth would you include BIRTH OF A NATION on the list of influght movies?! No one wants to be next to a seatmate watching that piece of racist garbage. I would have rated this flight 5 stars but seeing that in the streaming menu was upsetting and frustrating. This 2018. That movie should be reserved for watching in a historical context with commentary and analysis, not offered up to unwitting travelers as a perfectly ok thing to watch for entertainment. We don’t need more recruits to the kkk!!"

Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"

Cons: "After the first two hours of my flight (which I sleep through) I couldn’t buy a drink a soda or anything."
Pros: "individual TVs"
Cons: "it would be great if you could not use all those one-use plastic cups. waste is a real issue in the US and the solution is using re-usable items like washable cups. Unboarding was a nightmare and it started to get really hot waiting to get off."

Pros: "Very friendly crew with a clean plane!"
Cons: "N/A"
Pros: "This was my daughter’s first solo travel home from college. She said the staff was helpful and kind. She loved that the flight was not over crowded. It was a smooth flight."
Cons: "Only negative thing she could say was her flight was delayed an hour. But that isn’t terrible considering all the holiday travelers."
Cons: "Wheelchair shortage on arrival, although I had one reserved. Waited for a while then walked. Not ideal. Very long wait for bus to rental car center."
Cons: "We thought we were flying AirFrance as our emails came from them and were surprised to learn after waiting in the AirFrance baggage drop queue for 30 mins that we were in the wrong place."

Pros: "Flight itself uneventful"
Cons: "Lateness"
Pros: "Call back service was best part."
Cons: "Booked ticket through venture card points. This meant that the email address and phone number to contact us in the event of changes was mediocre information. I was informed from Tripit that the flight was delayed, not by Delta. Reservation personnel took logical course of action to find new flight for connection that we could make because of delayed initial flight. I would recommend that they first see if there is an earlier initial flight that the customer could make, then look at finding later connecting flights. We found out about delay 8 hours prior, so we had plenty of time to get to the airport earlier. Total delay required me to take additional day off of work."
Cons: "Didnt fly from San Francisco to Atlanta"
Pros: "It left and arrived on time"
Cons: "They didn’t have wine in such a long flight"
Pros: "Happy to get an earlier flight - and was put in ComfortPlus"

Cons: "Typical cramped plane, too many planes going out of same gate are simultaneously"
Cons: "Delta airlines has very poor costumer service. THE WORST I HAVE EXPERIENCED. I wasn't the only one feeling this way, I witness a couple people fighting on the phone like me. When my 1st flight was delayed I asked to be rebooked then and the delta employee insisted that I would make my connection. I didn't make it. This is not all. I could have gotten to a near city several hours after but on the same day, but the mediocrecy of this employes did not allow me to get there until the next day at 7 am. Happy new year to me. This two women (or one of them) on the phone, lied to me. There was an option to get me here and one of them failed to do their job right AND LIED TO MY FACE ON THE PHONE. Just unacceptable. I will sue them, I had an under age waiting for me in Cancun and a pet with me!. With no food or access to do its necessities. AND THERE WAS AN OPTION THAT "they missed" on porpuse."
Pros: "Friendly crew with modern plane"
Cons: "Why am I paying for first class for just snacks I can buy in an airport shop?"
Pros: "Food available was good."
Cons: "Very tight space- could not reach floor when person in front of me moved seat into recline position. Could not get out of seat to go to bathroom when my seat mates were sleeping. Tough to load- tight spaces."
Pros: "I was bowled over to learn in flight that the lowly steerage (economy) passengers--and everyone else had a selection of 3 complimentary meals! Who does that any more! Unfortunately, the only vegan option ran out just before my seat, but I was still amazed and pleased....and have ordered a vegan meal in advance for my next flight. Incredible! Plus, plenty of room for bags, good video selections, and power at all seats. I love Delta and will fly them more often!"
Cons: "The tsa is worthless"
Pros: "aircraft is very clean. faster than imaged. the most impressed thing is it has a variety of entertainment programs."
Pros: "The crew was really friendly and helpful. The plane was really clean"

Pros: "Easy flight. Plane and crew were fine"
Cons: "It was a short flight but no entertainment on this plane."
Pros: "Everything went smoothly."
Cons: "N/A"
Pros: "It was my husband's birthday and the stewardess (red dress, long brown hair) went out of her way to make him feel special by bringing champagne, cookies and even chocolate once we were getting off the plane. I was very touched."
Cons: "The guy next to me was kind of smelly but was very nice."
Pros: "Flight was on time and left and arrived on time."
Cons: "Should offer headphones for free."
Pros: "The service was fine. I slept the entire flight."
Cons: "I was not impress with the breakfast since I do not eat yogurt. It is a good thing i am not a breafast eater normally because I would have been hungry."
Cons: "Asked for hot tea but what I got was barely tepid."
Pros: "On time departure and arrival."
Cons: "Cramped! Cabin crew not particularly friendly."
Cons: "I tried to get a seat and it was so hard, i couldn't do an online check in and once at the airport, no one could help me."
Pros: "Painless"
Cons: "Price of food"
Cons: "Too cramped for a flight more than 90 mins - even in the "comfort+" section. This plane configuration is fine for much shorter flight routes"
Pros: "Staff was friendly but Stern with customers that needed it"
Pros: "Captain was informative but not too talkative. Left on time and arrived 20 min early"
Cons: "It was a 6 pm take off and the only food available for purchase was a “snack pack”. A tiny piece of beef jerky with crackers, cheese, and 10 Chocolate covered blueberries for $6.00. Made the mistake of not eating before and was silly to be expecting more from a discount airline I guess."
Cons: "Flight was delayed by almost two hours so I missed the flight from Denver to Charlotte. Because of the way this flight was sold to us and booked through Kiwi.com, there was nothing that could be done to get me on another flight. The only option was to wait for a Frontier flight which wasn't available until Monday morning. I had to book another flight on a different airline at a cost of $600."
Cons: "Negative leg room, Hugh bag fees that were not stated in the original purchase"
Pros: "the price"
Cons: "the stressful environment with screaming babies/toddlers (six of them) the whole way non-stop"
Cons: "My flight from SFO to Denver was canceled and I missed this flight. Had to pay more money for a mnother flight."
Cons: "Flight was delayed 6 hrs while other flights to Denver kept taking off"
Pros: "Low fare! I pack light, so I could fit everything I need into a "personal item" and saved on bags. Boarding went pretty smoothly."
Cons: "Seats do not recline! Bad news on my redeye flight. There were 4 dogs on this plane that I saw. Possibly more. Is there a limit to allergen producing animals on one plane?"
Cons: "The flight was delayed and we got a notification from google, but when we called Frontier, they said it was on time. And when we reached the airport they said, its been delayed. It caused a lot of inconvenience. Very unprofessional."
Cons: "Carry on bag cost of $45."
Pros: "Simple flight"
Cons: "Bumper approach coming into Denver. No snacks or beverages"
Pros: "They oversold the flight and bumped us from it. We didn't make it home for the holidays."
Cons: "Flight was cancelled!!!"
Pros: "Clean, friendly staff."
Cons: "Seats did not recline, so it was impossible to rest during this long, middle of the night flight. Misled about cost of carry-on."
Pros: "Flight was good and landing smooth."
Cons: "No beverages or snacks were offered. The flight was a late night flight and there was no where refreshments or beverages could be purchased, hence I was forced to fast for 6 hours."
Pros: "Literally. Nothing. Showing up at my destination alive, I guess."
Cons: "2 hour delay, then a three hour delay bc of weather. Another 45 minutes taxi-ing, then back at the gate because a passenger had to be escorted off because he didn't have a boarding pass. We were rushed to board he flight in the first place before the flight crew timed out; we finally took off at 2am with exhausted pilots which was terrifying. Also frontier charges for all bags and all seats, instead of including it in their base fee. Plane is tigjt and uncomfortable, no on board entertainment and seats don't recline. Most passengers were drunk and rowdy after long wait at the airport, and a man was busted for smoking weed in the bathroom. And someone else sat in my seat. THE WORST FLIGHT EXPERIENCE I HAVE EVER HAD--an all around disaster."
Cons: "The plane looked old (chipped paint, outdated upholstery). Seats did not recline. Had to pay for all baggage, carry-ons and drinks/food: this greatly increased the price of what we originally thought was a good deal on our flight."
Pros: "The flight arrived 40 minutes early."
Cons: "I paid $40 for a carry on. The plane was not pressurized, I've never had my ears hurt to bad on a plane."
Cons: "Seats comfort is not very good. Tray tables too small."
Pros: "Leg room that I paid extra for"
Cons: "Staff very rude, continuously asked if the passengers next to me spoke English even though they obviously did, very uncomfortable chairs"
Cons: "I use to love Frontier back in 2006-2008. I purposely booked the trip on Frontier as they were known to be clean and comfortable. Much to my surprise the plane was very very small, the seats did not recline at all (horrible for an overnight flight) and the trays were so small I couldn't even fit my laptop on it."
Pros: "Polite and efficient"
Cons: "Comfort of seats. Price of ticket and charge for carry on"
Pros: "New plane"
Cons: "Held on Tarmac for one hour due to gate troubles, charged 40$ for carry on, they only serve water for free, everything else is charge, no internet on plane, seats don't recline, check in kiosk not working and no attendant at checkin desk until 715 for 915 flight, very bad overall experience"
Pros: "Staff was great. Flight was comfortable. Loved having an all female crew."
Cons: "Flight was delayed due to mechanical issues. This is very frustrating."
Cons: "We sat on the tarmac for about 1.5 hours in Denver before we could leave the plane."
Cons: "Be warned--this airline charges for EVERYTHING, including drinks in flight and carry-ons. After spending nearly $100 on bags, I had to wait over an hour in baggage claim before the bags made it to us."
Cons: "The flight was cancelled. No big deal. It happens. But the the manager at the ticket desk took two hours to figure out a solution. His "solution" was to print out a phone number, hand it out to each of the passengers and then tell them to call because "there was nothing else he could do for us". And then he left to some back office and didn't come back out. The phone number he gave everyone was out of service. I called the regular customer service and asked them to help me rebook a new flight. They refused and said only the employees at the ticket counter could assist. The ticket counter people offered a refund over and over. But why would I want a 100 refund when I needed to book a 3-400 dollar flight to get to my destination. About eight hours, a couple of yelling matches, getting hung up on twice, and several actual tears later, I finally got a flight booked but the earliest flight they could find was 24 hours after my original scheduled arrival time. I'm writing this thirty minutes into my wait for a hotel shuttle. Long story short, I will take a greyhound or catch a cab or walk to my destination before I ever use frontier again"
Pros: "Friendly staff."
Cons: "Got delayed almost one hour. Seats didn't lean back. No snacks included."
Cons: "Schedule delayed twice, huge baggage fees for carry on, poor customer service, terrible and thin seats - gum all over plane"
Pros: "staff and crew were friendly and communicative."
Cons: "plane was delayed. boarding was weird, but i think maybe just because of construction at the airport."
Pros: "Nothing"
Cons: "Flight was cancelled and airline didn't do anything to help serve its customers get on another flight until nearly 24 hours later."
Pros: "It's really hard to find anything positive to say."
Cons: "Checking, lack of communication during delays, rude crew members, getting yelled at for not sitting while another plane is obviously docked at the gate we are suppose to pull into for an hour. Everything just really sucked not work the price you end up paying with your time, add ons and convenience not worth it."
Cons: "Charged for every additional thing so the cost of the ticket was not true."
Cons: "Flight was 3 hrs late...plane dirty"
Cons: "Flight left 45 minutes late with no alerts, uncomfortable planes, tray "tables" couldn't hold more than a deck of cards and a small coffee, nickel and dime for everything, no wifi"
Pros: "Efficient boarding, arrived early"
Cons: "Had to pay extra for everything--seats, sodas, bags both carry-on & checked. Seat tray miniscule"
Cons: "The Extra Fee's. I thought i was getting a good deal when I found my flight, but adding on an extra 170 for bags and paying for seating was a shock. I could have saved if I had chosen another airline.."
Cons: "The seats, the service and having to pay extra for everything!"
Pros: "Nothing good to say."
Cons: "The boarded us twice and deplaned us twice. The airplane had mechanical problems and took them more than 12 hours to fix, because it was missing a part that was going to take them more than 8 hours to get in our airport (not sure where the part was coming from that took them that long). After fixing it the crew couldn't fly because of federal regulations that states the crew can only work for 8 h. After this whole ordeal, my flight ended up cancelled."
Pros: "???"
Cons: "The seats are like benches. I had to have a body massage as I arrived due to body ache There was no food Paid $40 bucks for my carry on"
Pros: "The crew was friendly and the plane was clean. Seats aren't too bad either."
Cons: "This is the only airline I know of that charges for a carry on bag as well as non-alcoholic beverages. Also, the charging for seats is ridiculous."
Cons: "Hidden seat and carry on fees. Come on now. What is the likely hood someone doesn't have a bag flying 2500 miles. You're going to charge for that in addition to the ticket? Plus, yes plus another charge to select a seat. Super dumb and honestly a bit childish. Put your entire price online and let people pick. Also note zero wifi. I know you're a lower tear airlines but it's 2016! Give the people the all in price and if you won't give them entertainment or wifi make worth their wild. Also note, the tray table was about the size of a tablet, I couldn't even use my computer to do local work during the flight. I appreciate the safe flight but from a high level: 1: make your online prices more transparent. 2: if you're going to be lower tear, make it clear that wifi and infighting entertainment isn't included. People will still choose to fly cheap, but to burry hidden charges is horrible."
Pros: "If Kayak wants to boost its website it should give overall projected costs for flights not just bare bones prices. Frontier is the biggest nickel and diming company since Ryan Air. What a disgusting and dubious way to run a business. Worst experience ever. I have had and continue to have status with at least two of the large carriers, so I have flown a lot. Too bad no one else could provide the direct flight to Cincinnati."

Too bad no one else could provide the direct flight to Cincinnati."
Cons: "I took off time from work today to catch a 5:25 flight from San Francisco to Denver, arriving at 9:05. It's now 11:55 pm and I am still sitting at gate 21 with a whole bunch of people other waiting for a plane to arrive. My only choices are to wait of this plane to show up, or come back in the morning to take the 5:45am flight. I have business meetings in Denver tomorrow morning. I had a car rented and a hotel reserved. The car rental in Denver closes is 5 minutes. The thing that's the most upsetting is that we keep receiving erroneous information. The original departure time was 5:25. Then we were told 6:00. Then we were told 9:00pm. Then we were told 12:03, Then we were told 12:20. Now we are being told they don't know when the plane will arrive to take us to Denver. I will NEVER fly Frontier again."
Cons: "Since frontier has went cheaper they have become one of the worst airlines. My first flight ran out of water for the bathroom and my second flight we delayed because they had to duct tape the bathroom door back on from the flight before mine."
Pros: "The staff was very helpful, I needed assistance and they were there to take care of my needs."
Cons: "How the airlines charges for everything except water."
Pros: "Nothing"
Cons: "Service, seats, everything...not worth the cheaper price"
Pros: "Crew members were fun."
Cons: "The plane was super old. And none of the chairs reclined. And the big surprise was the $35 fee for carry ons lol. Like seriously?"
Pros: "Landings were very smooth."
Cons: "1. Charged $40 for carry-on (each way) 2. Charged $2 for tea. 3. Charged $20 to choose my seat (each way). 4. Flight was 90 minutes late (on a 2 hour flight), no explanation given. 5. Flight delayed another hour due to mechanical problems, no compensation offered, tea still $2."
Pros: "Good price, early arrival"
Cons: "Rude service at checkin by Keisha and cabin temperature during boarding was in the 80s"
Pros: "The crew was awesome."
Cons: "Extra hidden fees for baggage, food, and seating. Next time I would opt for the more expensive flight for more comfortable ammenities."
