So, when I booked my flight for next week, I booked a one-way. Normally families buy round trip tickets, then just pay a penalty to have the return flight date changed, since you book without knowing exactly when you're going to be ready to return.

My agent from Golden Rule said the airline, Lufthansa, has been increasing their change penalties, and it's now to buy a one-way there, then when you know the date you're going to be able to return, purchase another one-way home plus the child's ticket.

But today a parent headed to Ukraine ran into problems at the airport when she wasn't allowed to board the plane without proof that she was only going to stay in Ukraine under 90 days. Not having anything to prove that, she was forced to purchase another ticket, which was exorbitantly priced.

I know several other families are getting ready to travel soon who have also purchased one-way tickets. Is there anyone else who has recently traveled who has run into similar problems? Anyone who is traveling to the same country as me, who has gone on one-way tickets and not had a problem?
