Airline reviews

The flight was great. The pilot was great. It was really annoying that the staff had facemasks on. Hard to hear what they’re saying when a mask is covering their mouth. I enjoyed the flight, but there was a crying baby in front of me. You guys should offer flights baby free. I would be very into that me and the person next to me discussed how they should make free flights for all of us that don’t have kids. I wouldn’t mind paying extra to not have to deal with the smell of a dirty diaper or screaming of a child. Also, if they had a separate room, the babies could be sent to the back with a curtain or something muddle the horrible sounds.

Smooth. Courteous. Fun. One problem: the wheels on my checked roller back were broken when I picked up baggage at destination. Must have happened during flight baggage handling but I don’t know where.

Staff very helpful and friendly, in flight entertainment poor. Flight left late and thus arrived 20 minutes late to final destination.

First time flying with Alaska and the staff were All professional from checkin to departure! I do plan to book more flights with Alaska. Thanks

Boarded the plain and had to wait 1 hour for crew Captain to arrive from another flight

Overall good flight, smooth and on time and comfortable. Disappointing that food is not served and you can't purchase the snack packs on the plane.

There was a row with three women who were very loud - talking and laughing. In an open, outdoor setting that's fine. On an airplane, no. The flight attendants told the women they were the fun row. It took the woman sitting in the row ahead of the loud women to tell them they were too loud, but everyone in the general vicinity was irritated. I didn't think it would be possible to be so rowdy for so long. Then when we landed we weren't let off at a gate. We had to be bussed in and the bus contended with airline traffic. After dealing with the loud passengers, this was not what I was expecting. An incredibly disappointing experience with an airline that I have always regarded as one of the better ones.

They oversold my flight by 9 seats so when I went to check in I was not assigned a seat and the only one available if I didn’t want to chance it were 100 dollars more

Was not happy that we had to wait an additional 50 minutes for passengers that were still in TSA. This delay made us miss our connecting flight in Seattle to get home to tuck in our two little toddlers. We ran off the plane and ran across the entire airport trying to make this flight only to get to the gate to see that they have ended boarding. So they were willing to wait for passengers in Hawaii but not Seattle?? Especially when this wasn't even our fault. I expect to receive miles for missing our flight and spending an additional 4 hours in Seattle.

Better organizing of entry and exit onto the plane regarding all of the baggage people haul on. There should be a better system so those with no baggage can get in and out more quickly. The baggage haul-on situation is absurd.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money
