Lost one piece of luggage even though I checked in 2.5 hours before the flight

Lost one piece of luggage even though I checked in 2.5 hours before the flight

It was Swiss. Our kosher meals were literally frozen solid and therefore inedible, and the crew didnt care.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

We used Kayak to reserve our tickets and specifically checked the luggage option which was a more expensive option. When we arrived at the terminal we had to pay an extra $90 per suitcase for the three passengers. This has been a pattern for the past 3 years. Why charge for a more expensive luggage option, and the ticket price not include luggage?

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

American Airlines is a great dependable airline, on time arrival and departure with polite crew and staff.

I think since I am an AA Advantage member, my checked bags should have been free, but I paid for all 4 of us.

This flight moved Gates several times in a short time period, from B to C, which required a substantial walk or rail ride. Then the flight was delayed more than 2 hours and the food was subpar compared to other flights.

Flight was delayed multiple times without giving any particular reason and the only thing that was communicated was that 'Aircraft is getting ready'. I was stuck at SFO airport for 15 hours and finally took Southwest Airlines flight back home to Dallas.

Hydraulic leak caused the flight to be cancelled. Auto system scheduled us on a 3 am flight. Wevhsedvrebook on the app and hit schedules later in the afternoon. Our luggage per gate and ticket agent would be rescanned and put in our new flight. Did not happen. Our luggage stayed in hsv. Baggage claim in wash dc unable to help. We filed a claim. Several emails about our luggage were in conflict with one another. Called as baggage and was on hold 30 minutes. Oscar said one of 2 was out fir delivery then cancelled. About 45 minutes later both pieces were delivered. Their system is suspect

I was not clear if food was offered or not.

Because I bought my ticket from Underpricer, I could not check in online. I could only check in at the airport and that was deeply frustrating because I had to arrive very early. The flight also departed 45 min late and passengers were given no explanations about why we were delayed. I was worried I would miss my connecting flight. Once on board, however, the flight was fine.

Absolutely terrible. They boarded the plane, supposedly realized they didn't refuel the plane or load the luggage so we sat as the gate inside the plane for over 2 hours while they supposedly did things that should have been done before having passengers board the planem

Flight cancelled. Twice. And no communication. No gate agent. Went past boarding time and had to go and see email from AA. Airport communication was bad

I love the e fact that the staff communicated swiftly when my flight was delayed and gate number changed
