After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

We were delayed for a “couple of maintenance issues.” They were resolved rather quickly but a computer glitch caused someone in the airport to have to bring a physical copy of the paperwork so we could leave. I don’t know where they had to drive from to get to our plane but it took forever & we were 1 1/2 hrs late in leaving. The flight itself was fine.

You can plug your phone in & use their wifi to watch movies, etc, but the plane’s wifi was disconnected for most of the flight.

We had 3 flights. 1 & 2 were on the same plane but we had to de-board just to re-board 30 mins later. That may have been due to a crew change though. Our 3rd flight had a couple “maintenance” issues that held us up. They were quickly resolved but it took forever for someone to bring the paperwork needed so we could leave. Apparently there was a computer glitch so a driver had to bring a physical copy. It delayed us about 1 1/2 hrs. The flights themselves were smooth & no problems. For boarding, I don’t know why they don’t start with the back of the plane & move forward. It would eliminate the back up from people trying to find their seats & put their bags in the overhead bins. Unless you’re on an overseas flight, there is no food, you get a beverage & either a small bag of pretzels or a biscuit cookie. Take your own food or snacks of you want something more.

Very below average , plane from Dallas to Toyko was very poor designed plane. I had to sit for 13 hours next to fat man. Really bad seat and entertainment screen sucked

It was a red eye flight, so no meals were provided, but it was fine with snacks. The seats felt cramped and almost too narrow.
