The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

Even though we were delayed, we were able to make our connection

I still prefer Delta, but Delta doesn’t fly to State College PA.

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.

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

Ok so apparently the new policy on United Airlines is that customers in the main cabin should NEVER be served more than once and besides picking up trash there should NEVER be another interaction with the customer for any reason.

Cleared standby and gave up my seat. Terrible policy and boarding experience

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.

Did not get any refreshments. Crew was very nice but limited. Small seats

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

temp inside the plane was very hot and could not be adjusted.

Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.

Wheelchair was waiting for me,changed to a better seat which was great as it's hard for me to walk
