The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

Initial flight was cancelled at the time of arrival to the airport, flight alternative requires switching from direct to flight with a layover, and the plane felt like it would split apart, it was so rattle-y.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

AA re-routed flight from HNL to LAX due to delay. My group of 3 with reserved seats in row 9 was broken up, with one assigned to a middle seat, another in the last row of the plane. Not happy. No explanation to the delay. No apologies. No compensation. Would have been nice to be offered an Admiral Club admission or a voucher for the extra 3 hours of layover in LAX. Could not hear the boarding gate announcements in LAX. Adjacent gate was boarding at the same time. Loud speakers were competing against each other. Barely made my boarding group.

Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.

Above and beyond effort from this crew in a tough situation. So helpful and understanding. Thank you!

The flight delay in Dallas created a domino effect that impacted all connecting flights, leading to an increase in the number of connections. As a result, I missed my flight from Casablanca to Marrakech due to the tight turnaround when landing in Casablanca. CMN Airport was understaffed; only one employee was available to assist passengers while others just stood by and watched. It was an extremely frustrating situation. Many passengers were crying and banging their hands on the counter while talking to customer service representative Allabough. Unfortunately, Allabough couldn’t change my flight in the system. At the same time, I was on the phone with an American Airlines customer service representative named Solomon, who said he couldn’t make the change either. So, I decided to take an ONYA Voyages train from Casablanca to Marrakech to reach my destination on Friday, June 26. It turned out to be an unpredictable trip.

The flight was fine and the crew awesome. The problem is ORD and AA. Computers went down, ORD fell apart and a 40 min flight turned into a 3 hour trip. Guess the answer is to not try and fly to ORD after noon. But, as I said, crew was awesome and did everything they could to lesson the flight time.

Almost a 6 hour flight and the only food option is a cheese plate… and chips. Also how is it there are no options for texting on American. I’ll be going back to delta and united.

This flight never occurred because AA couldn’t get their act together.

Tight! Seats are not designed for those of us who wear extra-large clothes.

The non-stop flight from Grand Rapids was excellent. I neither expected or needed a budget flight and Allegiant made the trip easy and for an affordable price, Arriving at the Mesa Airport (AZA) is a delight compared to the international airport. For our return flight, we were able to arrive 75 minutes before the flight, return the rental car, check our bag and make it to the gate in plenty of time. That would never happen at most airports.

Easiest flights I’ve ever taken. Plane was comfortable without overly crowded seating.

Terrible. Still have not received the refund from them. They sent it to some account that I don't even know. Spoke with costumer service and they are unable to help.

I didn’t like it at all. I miss my second flight because of the delay on Allegiant Air now I m stuck in MCO.

Good, but a bit late on take off after loading. Don't like charging for carry ons!

First time flying with them and will definitely fly again in the future. Crew was so nice and friendly, fought was seamless. They are simple planes, no entertainment, but it’s fine for a short flight or if you have personal devices Rates are competitive, and they did so well with keeping the flight on time after a tropical storm, where other airlines had delays and cancellations.

They boarded passengers that sat in the back of the plane first, making boarding very efficient.

I didn't even take this flight. My plans changed and I couldn't get ahold of customer service and the website kept breaking down during the attempt to change the flight. I wound up taking another airline entirely and eating the cost.

The worst flying experience ever 3 delays. No accommodations. Had to deboard the plane after being delayed.
