My wiveswife's passport expires in 3 months and she didn't know about the rule that you can't fly to Europe if it expires within 3 months. We shortened her stay by a few days to accommodate this. My question is, once we are there are we able to book a flight home later on even though the passport will expire in less than a few months? I know it's probably not technically allowed but once we're there can we get away with it?
