In that case, you’re likely to be a passnger on the next flight to your point of departure. The rules are clear and IOs the world over are paid to enforce them. So, I strongly suggest you do not take the risk of landing with insufficient funds. You may get lucky and end up at the counter of that IO that doesn’t care about POF, but no one can guarantee that.So what happens next when you are short of what is the minimum amount and they checked for proof?
All the best
