I booked a holiday for two with a budget travel agency. They needed the names and passport details of the people going. I gave them my girlfriend's name, but she was in the process of getting a new passport.
She still hasn't managed to get one, but her old passport with her old name is still valid. So we asked them to change the booking to be under her old name. They said they couldn't possibly do that for less than £50, and I told them not to bother. We gave up on the holiday. (We didn't say to cancel, because we couldn't get any money back, and the option of me going alone was still available.)
Now we've received boarding passes in her old name, which her passport is under. So it seems that they must have provided the airline with her old name and her passport number, and we're good to go, despite what they said.
But the boarding pass doesn't have a passport number on it, and when I go to the airline's check-in page (ryanair), I can't find the passport number associated with the boarding pass (mine or hers). (I can find the boarding pass itself.)
So I just want to check: if we've been given a boarding pass, does that mean the airline has all the details they need? Or might something go wrong?
