Airline reviews

The flight delay in Dallas created a domino effect that impacted all of the connecting flights. It also increased the number of connections. I missed my flight from Casablanca to Marrakech because of the tight turnaround when landing in Casablanca. . CMN airport was understaffed. Only one person could help while other employees were just watching him. It was an extremely frustrating situation. People were crying and slamming their palms on the counter when speaking to the customer service provider, Allabough (man’s name?). Allabough couldn’t change my flight in the system. simultaneously, I was on the call with America. Airlines customer service rep named Solomon that said he couldn’t change it either. So, I took a ONYA voyages train to from Casablanca to Marrakech to get there on Friday June 26. This was unpredictable trip.

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.

Terrible. Cancelled my original flight. It made getting a boarding pass difficult. The AA employee (in a loud voice, so everyone around could hear) griped at me for not getting a boarding pass 24 hours before. I asked how I was supposed to do that when I had no idea what flight I was going to be on. She said (loudly), “Talk to AA customer service, not me!” I could certainly tell serving customers was not important to her. Our new flight was set to a completely different city. We had to change our rental car, and the price went way up. It took 2-1/2 hours to get checked in. By then our new flight had left. We ended up on stand by and had to split up the family to get to our destination. It cost us the whole first day of the trip. AA needs to employ people who actually care about doing a good job. I suppose those people are getting harder to find, but atleast try.

Am still mad at American airlines. You should know it's us travel nurses who are your customers and you treat us like nonsense it's not ok. American airlines took my money, no refund for whatsoever. A trip that was of 466 and I paid 466 and 833 then they chose for me where to sit and refund my seat choices and gave me expensive seats for 79 USD. Kayak doesn't help at all after booking you are on your own. Skyscanner is better

Bad food, small seats that didn’t recline. I thought I was buying a quantas ticket so I feel like I got scammed

This was a horrible experience. For a first class experience, my chair was held together by 3M tape - and I have a photo. The crew weren’t very attentive, somewhat dismissive and forgot my drink and snack, the chair reclined about 3 inches on a 6-hour cross country flight. I was also not informed that there was no lounge available in Newark airport because of renovations, so all around this was one of the worst experiences and I would actively avoid both American and Alaska Air going forward.

The flight was fine but the 8 hour delay in Chicago was awful - 5 gate changes and repeated delays without an explanation. No vouchers. Nothing.
