Airline reviews

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

Gate agents were informative and friendly… flight attendants were as well. Had a fun time chatting about their legacy AirTran experiences as a former fan of the airline that Southwest acquired.

Flight was awfully bumpy and landing was a bit jolting. I was in the restroom when snacks and drinks were served and was not asked if i wanted any. I had to ask for water finally.

Wi Fi was horrible kept cutting out the whole time and too expensive

I really like open seating. I hate that I've heard this is going away. This is one of the unique things that makes Southwest my goto choice.

Boarding was a little late, but made up for it. It was quick to taxi to the runway, since it's a smallish airport.

Excellent! Only question is how we check in at exactly 24 hours in advance and end up at the end of the B boarding group

Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

It was 2 hours 45 minutes late, for no apparently clear reason.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

Terrible. First of all we were delayed 4 3/4 hours departing Honolulu. As we had to leave our condo and the rental car had to be returned we had to go to the airport. Even though we had a business class boarding pass to Washington, since we did not have business class to Montreal we could not access the lounge without paying a $59 fee each. This does not make sense to us. Since we could not meet our original connection United booked us to Montreal via New York LaGuardia on Air Canada. In Washington a further delay got us into LaGuardia too late to make our connection to Montreal so we were booked on another Air Canada flight 3 hours later. We were originally scheduled to arrive in Montreal at 10:40 and arrived at 19:55. A totally exhausting day, United did not offer a meal voucher or any type of compensation. Air Canada did give us a digital meal voucher. The food in United business class is poor among all meals offered. The pods look nice but are not that confortable. Overall would not fly on United again.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Our seats were all the way in back of the plane,

Food choices were very limited. Taste of the dishes was average.

Maybe add a seat trade app for flyers that didn’t get seats together

The boarding experience was good; $20 for wifi per flight is uncompetitive compared to Delta, Southwest, and others, and puts American lower on my list given similar pricing.

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Delays on all NY flights. There was no communication on why but they didn’t say it was weather. Other carriers were not delayed.

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.

I flew out of Reagan National. My flight was delayed, delayed, delayed, and then canceled ...THREE TIMES over TWO DAYS. Staff were seemingly not empowered to provide information on why the flights were screwed up. A real nightmare.

They cancelled our flight without warning OR a refund. Never doing business with American Airlines again! This is the second AA booked trip in a row that we've had challenges with.

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Flight delayed on both ends - have a gate ready at DCA, don't make us sit for 30min after being late to take off as well.

The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.

Multiple time changes, then we left earlier than we were told.

Communication could be better but the staff and crew were over the top friendly and helpful, The flight itself was smooth.

flight was cancelled literally at 10pm the night before an early morning flight with hardly any time to reschedule. Will never book with kayak again.

My flight was cancelled 12 hours before takeoff. I was not able to reschedule another flight to make connections and had to cancel the entire trip. The ticket that was supposed to replace the cancelled flight had no boarding pass and I was unable to get one at the airport so I was denied access to the rescheduled flight. I was refunded but I missed my daughter's birthday.

I had a family emergency and couldn’t make the flight, and they wouldn’t let me cancel/refund it (a *month* ahead of time), were especially difficult with me on the phone, and wouldn’t let me even so much as reschedule the flight or get credit.

Flight was cancelled, communication was poor and should have canceled flight much earlier.

Flight was cancelled twice. Moved four more times. Probably the least timely and poorly run airline I have ever experienced in my life. I have traveled hundreds of times to dozens of countries and this one takes the cake.

Excellent crew, good flight. Flight was delayed about 1 1/2 hours though.

Pros: "The ground crew and flight crew were great."
Cons: "Would have appreciated easier steps (lower risers) for boarding. Arthritic knee makes it hard for me to manage the high risers between steps. Also having armrests would have made the flight more comfortable."
Pros: "I loved the small craft and easy boarding."
Cons: "Flight is a little slower with a smaller plane, but that was expected."
