Connection flights should be spaced out farther because too close I missed my connection.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Gate agent was unhelpful for handicapped boarding. Flight attendant seemed untrained.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

Clean planes and not take my comfort class seat away.

Weather caused a long delay, but the efficiency and updates from the pilot were helpful. We were able to make our connection fortunately.

Planes were clean, no water or snacks on either flight.

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

I flew from Santa Fe to Denver to catch a flight to London and the transfer of my luggage on arrival at Denver to the London flight worked perfectly. The crew on the ground and on board for the London flight were so friendly and efficient.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

Boarded early, left early, arrived 40 mins early! A win win for me!

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

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.

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

The flight from LA to Chicago was smooth and service was very good overall.

The flight from Dallas to Tokyo was not on Japan Airlines. It was on American Airlines. Very disappointed that we did not fly on Japan Airlines. Will not be using you liars again. I’ll just book direct from the airline next time. Wish you could make this right and has us fly on Japan Air when heading back home to the US.

The Mario was so helpful and provided amazing customer service however l have being waiting for a callback for almost a week now and have not heard anything further after l informed them l wanted to change my date of traveling because of my hospital appointment even send them proof and l was unable to use manag your booking on their website is a bit frustrating and l would appreciate an update on My request as soon as possible. And have called them times without numbers no response

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

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.

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.
