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

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.

The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

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

The check in agents in PHL and gate agents had to have been the rudest women that I have ever encountered; the agent weighing the bags at check in screamed continuously at all of the guests as did the woman at the gate.I have Executive Platinum status with AA and fly a lot with AA but these ladies were the absolute worst I had the displeasure to encounter!

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.

The flight took off an hour late which made the connection concerning

My pillow had a shoe print on it, when I asked if I can have another pillow, I was told “I’m sorry but it is one pillow per guest, do YOU want to turn it inside out” to which I responded , no thanks I will go without. This is generally not ok, but For the price tag I paid flying business this is absolutely unacceptable. Hopefully American Airlines can update their accommodations to bedding that is not tossed on the ground and stepped on, or at least have a couple of extra pillows in hand, incase someone had decided to step on the pillows for what ever reason

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

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

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.
