Airline reviews

Cabin crew very friendly and pleasant. Flight left late but we didn't know why. Alaska Airlines app was not user friendly -- app wouldn't let us upgrade our seats, but no indication if flight was full. We wound up having to call the airline to request an upgrade and we were told none was available. Waste of time. Baggage retrieval was easy.

Cabin crew very friendly and pleasant. Flight left late but we didn't know why.

We wound up having to call the airline to request an upgrade and we were told none was available. Waste of time. Baggage retrieval was easy.

The boarding gate is literally just an aisle to the concourse. There is no seating and it's shared with several other airlines. It's crowded, hot, and standing-room only. It's difficult to hear gate announcements over the PA system with too many other carriers crammed into a small space. I've enjoyed flying AA in the past on the west coast, but the BNA single gate experience is horrendous! Never again from BNA to SEA with AA.

It was a partial full flight. But even with a spare seat it was hard to get comfortable More on me being a wide body probably

Our flights using Alaska Airlines went great! All of the flight attendants were very friendly. Big shout out to the pilots for getting us to and from our destinations safely!

I can’t complain. Perhaps passing out headphones, but it was on me to bring my own since I could have used some for my personal device.

I liked only the crew. The flyght was too much fast, faster than it should be, on 20 min faster, but not safer, I experienced on myself astranautic overload from suddenly appearing in the sky and all the vibrations of the turbines, because I had my place at the level of the wings. Pregnant woman should not be seated on the level of the wings with all turbines, pregnant woman should be offered to charge place to seat closer to front or in the back, but not at the level of all the turbines. Vibrations of turbines are not healthy for pregnancy. I hold all the flight my belly in my hands to avoid miscarriage. If it would be longer flying distances, I could have miscarriage with Alaskan airlines.

I didn't have food or use entertainment, so those evaluations are invalid.

I do not feel the priority seating I paid for was was adequate for the cost. there was no difference from coach on any other airline, and it was very uncomfortable

First flights on Alaska Air, and I will go out of my way to fly them whenever I can in the future. An incredible experience, above and beyond any other airline.

It was warm on the plane. Perhaps the people who were coughing quite often should be encouraged to wear a mask?! It was a long 4 hours.

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

No food or entertainment because it was a short flight. Unfortunately the takeoff was delayed more than an hour

Parents with kids should all be in the same area. Sounds rude but who what's to fly 6hrs with crying and bratty kids. Just my opinion.

Ok, so I didn’t have seats, so got there very early. I was first in line only to be told, listen for your name for seats. The flight was boarding before they gave me a middle seat, way after others showed up who were given more favorable treatment. Ok, so , don’t show up early and obey all the rules??? Clearly, your gate clerks did not. What gives???

Short flight but delayed. Since its a short flight no food or entertainment necessary

We had an awesome flight attendant who came by and made sure we were okay. Checked on us often and even shared some snacks that she had brought on, like edamame with chili and garlic seasoning. Yummy!

Overall good experience. I'm just over 6ft with long legs and legroom could be better, but is on par with other airlines. Only real negative was turbulence but that's not the airlines fault.

First flight got cancelled. Got booked for another flight departing 3.5 hours later which ended up being 1hr delayed... The flight was good when we finally ended up flying.

Very friendly und helpful crew. Looking forward for some more flights in

My husband and I had to split seats and I did not like to seat at the window.

Pilot and first officer did really an amazing job. I can best discribe their flying as finesse. Inital service with food/beverages was great, however after that the crew just kind of packed it in and were sitting in the galleys chatting for the remainder of the flight. I wanted a bottle of water, went to the mid plane galley, was told they were only available in the back, so had to walk the length of the plane just to get a bottle of water. That was a new experience on an airplane for me. Pretty sure evem Spirit will bring you the bottle of water you are paying for. Seat was comfy, magazine worth the read. Entertainment nonexistant unless you want to pop for the $4 headphones.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

On time take off…US cabins look tired and need of refresh!

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

28 hour delay at Fort Worth/Dallas airport, part due to weather which was unavoidable, but various other reasons - no pilot, no fa, mechanical problem, plane too small, too big, crew out of flying time, seat configuration problems.... endless and hourly updates with a different excuse. Finally told us about 3.00 am, that the flight was delayed to hours later.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

There were delays on both ends. It made it less than excellent. This plane was great though

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Was lucky to have a employee at the AA checkin counter that had compassion and understood they ordeal that we went through with our original flight being diverted, needing to stay in the aircraft and then flying to the original destination; adding hours to the trip and forcing us to miss our connection and our rebooked connection. She was able to get up on standby on the highest priority on the next flight to the closest airport we need to be at and it all worked out despite being many hours late.
