Priority boarding for one flight instead of two. I paid for priority boarding for my flights Vienna-Paris. After 3 days I got many emails saying that they add it to only one flight and for another one they didn't. I thought it was a joke because the whole reason why you're doing that - is you want to bring a trolley on board. But having it only one way doesn't make any sense. So, they refunded Priority Boarding for Paris-Vienna but left one for Vienna-Paris. I told them that pls refund me everything Priority Boarding for both flights. And they're telling me about the fact that they can't and telling me that it was a 'technical problem' to book Priority Boarding for one of the flights. So the operator was like, I cannot do it for the flight back, but who cares, let's do it for a flight to the place and refund a back one. How should I use it? I just have no words. Never using this service again. I simply have no words. Ofc they won't do anything about it. But it's not how service should work. It has no logic behind it.
