My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Good crew and flight was on time. It’s a small plane with limited overhead luggage space. They said the overhead space was full and I had to check my bag. There was still space when I got on. Waiting for my checked luggage added 30 minutes to my trip. Not the end of the world but also not great.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

No enough space plus only allowing one laggage instead of two like other airlines.

Qatar airways ,boarding arrangements at Hamid international airport could been better

Two flight changes before the scheduled flight. On the day of the flight, the flight was delayed, which caused the connecting flight to be missed. Then, I was directed to another airport (CUN) and traveled to Tulum. American gave a $12 voucher for lunch. The least expensive item on the menu at a Mexican restaurant was $9.99. Driving to Tulum was a bad auto crash, and traffic was delayed two-plus hours. The bottom line is that we should have been at the hotel at noon, but it ended up at 11:30 PM.

Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

First time flying internationally with AA and probably my last. Not military friendly at all. Didn't allow free checked bag for military family members (dependents) on orders like other airlines. We were charged $100 for baggage weight overage (5 lbs!)even though we had military orders allowing us extra.. Didn’t allow military members to board early. Inefficient and long wait time to board. Seats are smaller and more uncomfortable than other airlines.. no drink service for over 7 hrs of flight! After initial meal was served, the crew never offered a snack or drinks until the breakfast's was served 1 1/2 hrs before landing. Overall expensive and poor experience for the entire flight.
