Airline reviews

I was on a small regional flight from Detroit to Philadelphia. When we landed the outside cruise needed to turn something off with the engine, which took quite a long time. Then, when they allowed us to get off the plane it was outside. They took their time, unloading all the luggage and waited till they unloaded all the luggage before they brought it over to us. It was 9 o’clock at night freezing cold out, and there was no proactive hustle to try to get people their luggage. It was really one of the worst experiences I think I’ve ever had with American until a manager came over. I don’t think they were going to even consider pulling the luggage over to the people that had been waiting outside for at least 10 minutes in the freezing cold.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

The entertainment options were at best, fair. It was exactly the same as my outbound flight. It would have been more entertaining if there were some series from Apple TV, HBO, Showtime or other carriers for me to catch up with.

The seat cushions were very worn so they were extremely uncomfortable.

Services, food products, and crew friendliness on American Airlines international flights is mediocre compared to Emirates, Qatar, and Singapore Airways. American does not do much to differentiate its product on international routes. Its menu options are similar on international flights. American Airlines flight attendants do not call elite frequent travelers by their names; American Airlines flight attendants do not seem to be motivated to go above and beyond in the service they provide. American Airlines personnel do not seem to take pride in their work.

Crew were all friendly and helpful. It was a short flight so just a beverage service with a cookie. After we were boarded the plane took about 45 minutes to leave the gate but it was New Year’s Eve so not shocking there was some delay. Overall good experience and very grateful.

Nice comfortable flight from Barcelona back to the states. The premium economy offers the extra room we need for my husband. The food was good and our flight attendants were excellent.

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

I paid for the seats in row 3 to embark and disembark quicker but the passengers in the 2 rows in front of me take all the overhead bin space so I am forced to put my luggage 5 rows back. I even opened one up right above my seat which had room but as I was going to fit my carry on a flight atendant said it "was reserved", Just giving my money to a regular airline next time.

Terrible Flight was cancelled last minute with no other flights available

I was not informed via text about flight delay and gate change. There should have been a notice by the original gate letting us know that there was a change. A half hour before original flight time we realized there was no one there and were told that the gate was changed so we ran across the airport (I was traveling with my aunt who is in her upper 60s) to try to make the flight and then saw that the flight was actually delayed an hour . If you can do something for us to makeup for this we would appreciate it. Thank you

Terrible. Spirit cancelled the flight with 3 hours notice and were absolutely no help getting another flight. Had to make my own reservation on another airline and arrived in Dallas 12 hours later.

The flight itself was great except for an air traffic controller delay. We left 30 min late but they made up most of the time in flight. The booking was frustrating, as we chose a certain flight and it was changed four times. We got to Orlando several hours later than the original flight we chose.

Terrible. Poor communication from staff about why we were trapped on the plane for over two hours before even departing. Terrible customer service from flight attendants. Incredibly uncomfortable seats

Crew was very nice. Take off and landing were great. Economy seats are not comfortable. Extra cost for snacks.

Less than acceptable. Family members had flights cancelled with no reason. Multiple hour delay, gate changes, poor communication, less than satisfactory. I will never fly with spirit again, which is a shame because it’s a budget friendly option but quite frankly with all of the hassle and hoops that come with flying spirit. Completely unacceptable.

Everything was terrible. Flight was delayed several hours, crew was abrasive. Stuck on runway for over a hour. There was an argument between passengers that nearly turned into a fight while waiting to exit plane, crew did nothing. Took nearly 3 hours to retrieve luggage at baggage claim. Lost an entire day of vacation. Will never fly spirit again under any circumstance

The flight from Boston to San Juan was boring since you guys don’t offer wings if during the flight. The returning flight was better offering WiFi to passengers. The food was horrible not enough on stock.serve paying customers better.
