Check your itinerary for specifics on any given hotel. Hotels also sometimes have early departure penalties. Review the hotel's cancellation policy carefully. Also, traveling on someone else's ticket is illegal. Making name changes on a car rental reservation could cancel the original rate and require it to be rebooked at current rates.
Hotels tend to allow name changes without affecting the rate.
Airfares Cost-Saving Techniques Discount airfare rules Factors that affect air fares. Every airfare has its own set of rules and requirements. Unlike unrestricted full fares, discount airfares have one or more restrictions that apply. If you've been quoted a fare, keep in mind that it can be different when you call back to buy the ticket. Since the deregulation of airfares in the 70's the airline industry has been free to increase or lower prices, change fare rules, discontinue existing fares or create new ones at anytime and without notice.
