Trying to check-in online for the return part (flying out with different airline) and I'm asked to pay an extra 10.99 Euros each for choosing seats. I don't want to choose seats, I don't care where we sit. I can't do that, I can't check online then, I have to do this at the airport. WTF. So do I spend 55 Euros for us or do we turn up earlier and check-in at the airport. Really annoyed.
