Priceline.com (Nasdaq: PCLN) announced today that it has extended its Summer Flights Sale through Labor Day (September 3, 2007). While the sale is on, priceline.com customers pay no booking fees for published-price airline tickets purchased for travel up to 330 days from date of purchase.

Every flight and itinerary is on sale, except those purchased through priceline.com’s Name Your Own Price® service. That means that, in most cases, priceline.com customers will pay less for their tickets than they would at other major online travel reservation services, including Expedia, Travelocity, Orbitz and Cheap Tickets.

To check out the Summer Flights Sale, visit http://www.priceline.com/flights/.

Customers choosing priceline.com for their airline tickets will enjoy other significant benefits besides no booking fees. In addition to round-trips on the same airline, priceline.com allows customers to “mix-and-match” their flights, choosing one airline and itinerary for the outbound leg of their trip and another for the return, also without a booking fee. Combining airlines can improve itineraries and savings, which is why approximately 20% of priceline.com’s retail tickets now sold include two carriers. When these types of tickets are sold through other online travel reservation agencies, or via comparison shopping site referrals, customers typically pay a booking fee.

Priceline.com customers also have the ability to easily package a discounted hotel and/or rental car from priceline.com’s collection of thousands of partner hotels and rental car companies around the world. Priceline.com’s unique Name Your Own Price® option can save them up to 50% on hotels, up to 40% on airline tickets and up to 30% on rental cars compared to published prices. Priceline.com’s Name Your Own Price® service is unique and different from fixed-price travel sites. With priceline.com’s Name Your Own Price® service, important details about your itinerary are shown only after purchase.
