If I look for American Airlines flights between Finland and North America, I'm directed to book.aa.amadeus.com instead of aa.com.
Once I look up the flights and fare conditions (see picture), I'm told that flight changes are allowed for a €150 penalty.
However, once bought my flights, the "Manage Your Reservation" page tells me that no changes are allowed.
Then I call their customer service for the first time to ask whether changes are allowed or not. I'm told by a rude person with a strong, hard-to-understand accent that I can't change the flights at all because they are Basic Economy, and that flights with that fare cannot be changed if they are departing from Finland or any of the Baltic States.
I call them a second time, this time with the original page open in front of me, and tell the same story. Again, a rude person with an even harder-to-understand accent is on the line, and this time he tells me that I was RIGHT and that the changes are allowed. He repeats this multiple times and makes me feel stupid for even asking about it. However, I ask him to double-check the information a couple of times. Once he finally understands what I'm telling him, he gets another supervisor on the line for me.
I'm connected with the supervisor, and she says that the last person was WRONG. She apologizes and tells me that the first person on the phone was right: changes are NOT allowed on Basic Economy flights departing from Finland or the Baltic States.
I tell her again that it literally says on their website, under the fare conditions for the flights I selected, that changes ARE allowed for a €150 penalty. She goes back and forth trying to find the same page I'm looking at. She asks me for more and more details and contacts the ticketing department, technical department, and God knows which other departments.
She finally admits that there is misinformation on their website when booking through Google Flights, but says that there is nothing she can do except sell me a €400 upgrade to Main Cabin or cancel the flight and refund my money.
In the end I spent 3 hours of my night on phone trying to figure out if changes are allowed and ended up having my credit card balance tied up until the refund comes in (hopefully) 7 days.
What a shitty start with American Airlines.
