Airline reviews

My flight home from Knoxville, TN, included a layover in Atlanta. I boarded the aircraft in Zone 5 and although there was limited overhead space, I was able to put my 'backpack' style roller-bag above my seat. Unfortunately, due to continued bad weather, we had to deplane. There were many people who would have missed their connection, so they rebooked. When we were re-boarding, the gate agent welcomed zone 5 and then made an announcement: All roller-bags for zone 5 passengers and higher will need to be gate checked. I promptly pushed the telescoping handle in and held my bag like a backpack. I was able to bring it on board, which was a relief. Upon entering the aircraft it became apparent that there was easily 40% open overhead space. There were audible signs of angry passengers who felt duped into checking their bags when in fact there were noticeably LESS passengers on the aircraft and TONS of overhead space. I'm not sure what kinds of parameters are used to determine when to cut off roller-bags from being brought on board, but it seemed deceptive and underhanded to have so many people get stuck checking their bags when clearly there was ample room for at least one more zone.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

Fast, lovely scenery, great info on the Delta flight screen about landmarks we were flying over. Great landing!

Delta needs to step its game up get a more reliable internet service. Internet service was non-existent for this flight.

The crew on this leg continue to be extremely helpful with my wife’s mobility issues. They also came by many many times to ensure we were comfortable and had drink some food.

The Pilot was one of the best I've had, very informative about turbulence and got us to our destination early

I liked the cleanness in the bathroom and good crew on board and at boarding gates. There was no Hindi (Bollywood) movies. The entertainment can be improved as it is one of the worst one I saw when I compared it with other airlines. The Mumbai to Amsterdam flight did not have any food for my family which does not contain eggs in it though we have selected “Hindu Asian vegetarian meal”

Friendly boarding crew. Better could have been a bit more substantial food for this 3 plus hour flight.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

they made me check my carryon. There was space in the overhead bins.

Cramped and uncomfortable seats. Not enough room for 6’2” person such as myself.

Pretty turbulent, but not anyone’s fault. They got us there. Impressed that they carried on with a drink service.

Everything went as planned. The only issue I had was with the gate C31 attendant. The person could barely speak English and was very difficult to understand.

American Airlines II: Delay Boogaloo. Multiple gate changes, delays, boarded and then MORE delays. I hate to say this won’t matter, but posting stuff about major corporations in 2026 is a post-modern “scream into the void.” Was multiple hours late coming home, so there you go.

It's very confusing because Kayak has it as American Airlines, but it was Hawaiian Airlines, but operated by Alaska Airlines. I had to go to the airport for my boarding pass because American said I didn't have any trips.

Seats were much more cramped then on the 737. Narrower and rows closer together. Flight was absolutely packed and the plugs under the seats didn't work. Was forced to check my bag even though previous flight had no issue with it.

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

Because of rescheduling, they had to put me on a flight that didn't go through Dallas

Packed commercial flight was as comfortable as can be expected

We were re routed due to a flight cancellation. We did not fly out of Miami. We originally booked first class and were moved to coach without being compensated.

2 gate changes, several announced delays, not enough room and seats at the gate. Many had to stand while waiting. The actual flight was fine.

American Airlines customer service was extremely poor. They canceled our flights multiple times. Then put us on standby trying to get on flights instead of booking us on a confirmed flight to get us home. So flight after flight we kept our hopes up just to be disappointed and stuck from a connecting flight. We had never been to Dallas so we were sleeping on the floor at the airport waiting to get home.
