They lost my bag and 24 hours later have yet to find it

Long delay, no gate agent at deplaning waited 15 mins at the gate. Baggage claim was wrong carousel and over 20 mins after arrival

Flight delayed Didn’t send second leg of trip itemerary First class was fair, but not great.

Nice to get moved from a middle seat to an aisle seat upon request, but why wasn’t I put in an aisle seat to begin with? The flight was not full.

They called me 2 hours before my original flight from SFO was to depart to let me know it was delayed and that I would miss my connection. They then rebooked on a different flight leaving a half hour earlier to a different connecting airport, so that I would not miss my connection. It all worked out and I arrived at my destination without a problem and 15 minutes earlier than the original flight would have. Nice!

Flight was delayed with no explication. There was ice falling out of vents on me.

Couldn’t order food for the family because all the good food was unavailable. We opted for bringing something on with us. I also didn’t like that I had to have T-mobile for online movies. Stupid.

Alaska is by far the best airline to fly with 😍

The flight crew home was so, so friendly and HILARIOUS. I’ll keep flying Alaska like I have for the last 30+ years!

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.

Heathrow is a nightmare in general (crowded, etc). BA was great - having to take a bus between the gate and the plane is a bummer.
