Airline reviews

The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.

Did not realize internet screen was hidden between seats and no info printed!!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

The flight was delayed for about 2 hrs. Other than it, it was good.

Advertised fruit trays with cheese, but only snacks handed out!

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

Experience was good, however I had a delay due to weather happening and had to re purchase a seat on a new plane for a higher price (could be my own issue and misunderstanding) but other than that situation. First time flyer (by myself) was terrific!! The last from ORD to ALO didn't have wifi, but it was only 45 minutes so I'm sure that was part of the reason. Overall my experience was great! Next time I will remember to buy tickets with longer layovers. The delays really saved my overall anxiety. :)

Did not understand a single word the attendant said on the pa system. I was glad it was not an emergency.

My flight was delayed about three hours. I got home at 3:30 in the morning very bad experience.

I had a positive experience on American. I'm blind and traveling with a guide dog and the flight attendants were so kind, friendly, and helpful towards us. They checked in on us during the flight and they made us feel comfortable and welcomed. There was an hour delay before depature, but overall the flight was a smooth ride. I appreciate that there were no issues on this long flight back home.

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

The flight was flawless and we even arrived between 20 and 25 minutes early!

Typically flights with AA are good. The staff are pleasant, welcoming, and efficient.

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

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.
