Airline reviews

The flight itself went well, except it left 1.5 hours late, and about 10 of us missed our Alaska Airlines connection by minutes; they wouldn't hold the plane, even though our arrival delay was caused by Alaska. No gluten-free options among the snacks; you had to order meals separately, but there was no consideration for food sensitivities. NO TELEVISION on a flight from Washington, DC to Seattle or from Seattle to Anchorage. I didn't know that ANY airlines offering cross-country flights didn't have screens for entertainment. This alone is a "never again" for me.

This alone is a "never again" for me.

I have to eat gluten-free due to celiac disease, but so far no Alaska Air flight has offered a gluten-free option for the snack given out with free drinks. It seems like that wouldn't be too hard to do.

I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.

Full flight where I had another passenger sitting in middle seat who said that he had lost 250 lbs from 500. The stewardess on exiting the flight advise me that I was going to receive a refund. I thought she was talking about another passenger. The stewardess saw that to make him comfortable I had lifted the armrest and flew for 5 hours to Seattle from Reagan DCA with a portion of his body on my seat. I survived. I flight to remember!!!!

the flight was delayed almost 3 hours and not one time was we told that it was delayed or why. I had asked one of the crew members why it was delayed, 20 minutes after the flight was supposed to take off, and was told that they had no idea what was going on and that they had not been told anything. this is FRIGHTENING!!!! No excuse!!

Flights were on time. Check in was fine. Crew members were pleasant.

I would have liked it to have been easier to order food for the flight. My son was not happy with the snack pack I bought him and it was a very long flight for a little boy to go without food.

Ground staff at LAX was very helpful. The Alaska lounge food and service is better than most airport lounges. I think the Staff are well trained polite and actually seem happy to work there. Great service Thanks 🙏 Jjk

The flight was very very delayed and arrived much later than planned. There was no communication about why or when our arrival would be. I would expect better and open communication about the flight but there was none. Also just pretzels? How disappointing.

I got to my destination but no comforts no snacks nothing. Like herding cows!!

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

9 hours of delay!! Was not able to check my luggage that I paid for!!!

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

I am very disappointed with Frontier Airlines. They cancelled our flight because they couldn't find a crew member, and then didn't get us to our connecting flight. We had to cancel our whole vacation. We were promised flight and hotel vouchers, but they never sent them.

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

It was ridiculously hard to check in for the flight, and Frontier charged us a LOT of money to have a carry on suitcase, and then told everyone we could not carry on bags and had to check them through at the gate, and didn't refund the extra money we paid to have the suitcase as carry on.

I had a terrible experience with Frontier. I arrived before the 60 minute cut off and was told that Frontier has a two hour window for bags. I was then told the next available flight wasn’t until the end of the day (I had booked a 6am flight). I took a look around and saw other people being told that they could not board their flights or that they had to pay additional fees. I opted to rebook on American Airlines. There’s absolutely no straightforward way to contact Frontier, so this ticket was a complete waste of money. Oh - and the kicker is that the lady lied about the two hour cut off.

Frontier won’t help you at the airport without paying $25. Carry on was $75. Then you get on the plain and every beverage or snack is also a charge. Seats are hard and real packed in. I would never fly them again.

Worst experience I have seen. The flight was cancelled without any reason.
