I'm not sure if someone else has the same issue as I have. I'm trying to book some flights through the website from AA. When I'm using any european websites of AA I receive the following error message:
Something went wrong.
We are sorry for the inconvenience, we encountered an error processing your request.
The fare for the flights you have selected is no longer available.
Please contact Reservations for assistance with making a new booking and quote “15012”.
American Airlines apologises for any inconvenience this may have caused. Start a new search: aa.com (15012) (15012) (15012 - 421)
I also tried the US website the issue there is that I would need an US address for my creditcard. If I change the country then I'm automatically redirect to my country's website and I have to start search for flights again. I also tried to pay with PayPal but also this one didn't work.
So It is impossible to book any flights for the moment. I contacted the customer service but I haven't got any answer until now. I hope they fix the issue as soon as possible.
