Great quik boarding, friendly gate agent and crew. Let early

We sat at the gate for over 30 minutes, with no indication as to why

All was fine. Small plane so no food or entertainment.

Very aggressive at the boarding area of only allowing one person passed a line/ sign

Delayed 7 hours Crew and employees were nice Extra long flight but at least we got in

I love how the flight crews are now saying what the weather will be like, when we can expect to be able to get up and use the restrooms etc. I have to say also that our flight crews this trip were incredible - fast and courteous - and somehow managed to do the service even on these short flights with a few bumps. The only reason for an ok rating on entertainment was because these short flights are on planes without seatback displays but that's ok because I just download shows on my iPhone beforehand.

Our flight from Detroit to LaGuardia on Thursday 8/20 was delayed from 555 to 910 due to storms and a ground stop at LGA. It’s never fun to be stuck at the airport but I thought the desk crew and captain handled it well and kept us informed. I especially liked how they referred to us as their “LaGuardia family.” I am a loyal delta customer and this is one of the reasons why.

The plane is old. There was water dripping fown from the air cooling system. The toilets were mot that clean

The meal tray was not usable it was completely uneven

Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.

Unacceptable pre-boarding ticket issues. Paid for and reserved Mint seat approximately a month in advance. Checked in to flight in Mint seat 24 hours before flight. Shortly before flight, was bumped out of Mint entirely, even though other Mint seats were still available and for sale. Was told it was "operational", however seats were still available/being sold. Got to gate and they could not explain it, but the gate agent was able to put me back into Mint (however to a different seat). Nothing proactive done by Jetblue, I would have been bumped had I not arrived at gate early enough to have a helpful gate agent rectify. No explanations from Jetblue.

The crew did not ensure the Evermore seats had their carry on space available. When my family and I boarded, we saw people putting their carry on suitcases in the overhead spaces above our seats and then proceed to the rear part of the plane. This resulted in us having to check our bags and being late to our meetings/events.

Crew was friendly. Free headphones would be nice. Free new movies would be better.

Diana at the gate was unhelpful which was fine, but she was also rude which I did not appreciate at all.

Nice plane, with TV, comfortable seats and leg room. Updated regularly on time changes

You should have had Wifi to make it much enjoyable.

The crew for the flight was A+ top notch. They were friendly and professional and made the flight a very relaxing and enjoable.

Flight was delayed by almost 5 hours. Suitcase was not loaded despite the flight being near empty (my colleagues’ suitcases did reach JFK, unlike mine). Had to argue on phone to get JetBlue to deliver the case to my hotel. Never again

Great. Loved that there was WiFi on flight to keep in touch and excellent service of beverages and snacks.

One of the worst experience. People from Saudi in general show nasty attitudes. They act like they own us. Or the world is theirs. Rude behaviors aren't acceptable. They have a bad accident and don't even know how to speak properly but they blame me for that and makes fun of me and laughs when I said I'm going to BANGLADESH.

The flight from Chicago to Orlando was delayed inordinately. My whole journey from Lansing to MCO took 9.5 hours is just annoying and frustrating. We can understand the delays may be beyond their control, but overall the journey was so much waiting until reached to MCO. This is NOT the first time for me - but at least 80% of the time in this route. I barely remember reaching places on time.

I sat in seat 22D near the back right of the plane. My phone battery was getting low, so I plugged my charger into the power outlets below the seats in front of me. They did not work. When I asked the flight attendant whether this was the case for the whole plane he said, "No. It's only this one. It hasn't worked for months". This should be noted to whomever services this plane so that maintenance can fix this for future passengers. I was on Flight AA5614 from Grand Rapids to Philadelphia on Wednesday, September 23, 2026.

The passenger in front of of me reclined their seat back all the way the entire flight. Their headrest was in my face the entire flight! I barely had room for the little plastic cup of water to fit on my tray table; can you make the seats and space between the rows any smaller??? You can’t even get up to use the restroom! Worst flight I’ve had in a very long time!

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.

It was a good trip. Flight Attendants were friendly and responsive.

The trip was very smooth and they provided great customer service

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

It was a crazy day with a lot of delays and gate changes. Not a huge fan of the Charlotte hub at all.

We have been delayed and postponed 2days and nights…and still do not have our flight until tomorrow..

American Airlines is awful!! Will never fly with them again. Connection flight left early leaving 22 people in Charlotte with no way to get to Key West for 24 hours. Would not provide hotel or any other accommodations. Bags were delayed two days.
