We have negotiated many different types of agreements with different airlines; thus, the rules and restrictions for exchanges and cancellations vary greatly if allowed at all. When allowed, airlines require that we collect a fee for the exchange plus any difference in fare when necessary. Exchange fees start at $125 and go as high as $350. Your exchange agent can tell you when you call.
These refunds are typically for seat assignment requests that could not be fulfilled by the Airline or during a quality check if we detected an overcharge. This refund does not affect your airline ticket purchase.

In Europe, foreign driver restrictions vary from country to country. Drivers need to be a minimum of 18 in most countries and have a valid US drivers license. Please check the official website of the rental company. These sites generally have age restrictions posted there, as well as information regarding seat belt laws, child seat requirements, and speed limits.
