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.

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 😍

They were flexible and able to get me home a day earlier due to a family members illness. Flight was on time and great friendly crew.

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

Deboarding the plane was chaos. The passengers in the back of the plane started deplaning before the passengers in the middle of the plane could even retrieve their overhead bags. The staff of the plane did nothing to help.

Enforce the one bag rule for carry ons. Don't allow people to have 2 and 3 carry ons. Make baggage gets loaded onto the correct plane. My bag didn't get put onto my last flight so I didn't get it until the next day.

onboard snack was pretzels, but the FA was super nice when my neighbor asked for cookies instead and also brought some for me. :)

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

It was a short flight so I was expecting too much

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

How can you rate a flight when it is canceled after you leave the gate & 3 hours into sitting there or in remote area of airport after mechanical problems

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

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.

Broken tray table. Erratic service. Premium economy is more economy than premium- other airlines treat PE much better. No lounge access.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

They made nearly everyone check their bag because the overhead bins are way too small. Extremely inconvenient

The overhead bins are too small, They served one meal and two snack for a 10hr flight. My meal was missing the butter, cheese and salad dressing everyone else got. The crew were nice and the plane was clean

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

The passport line was so long that many of us were concerned about missing our flight and some did. It would've helped if a AA representative had gone to the passport check-in sooner to advise that boarding was closing and those flying that were stuck back in the line, needed to come forward with apologies to others. An AA representative did do that but only after boarding had already closed. (They delayed take-off so that more who were running with carry-ons could get to the gate - especially stressful for older people!) Then to be crammed into a seat with barely enough leg room for a thin woman, 5'7", like me, much less for a taller, bigger person was not comfortable, especially if the person in front decided to lean back. Crew was fine, food and entertainment also.

Movies on my phone are great. It would be nice to have a gluten free snack option.

It was what i expected. I like the movies you can access from your phone. It would be nice if there was a gluten free snack offered. But I did bring my own snack knowing there would not be a gluten free option

The flight was peaceful, just s slight turbulence, pilots and crews were all nice and made a great job! Arrived safely in the Philippines. Thank you ya’ll!

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

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.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.
