Priceline.com?s summer flights sale is on! With one swift karate chop, William Shatner (aka The Priceline Negotiator) set priceline.com?s sale in motion today by cutting out booking fees for all domestic and international flights purchased by July 4th for travel up to 330 days from date of purchase. Every flight and itinerary is on sale, except for those purchased through priceline.com?s Name Your Own Price? service. That means that, for the duration of the Summer Flights Sale, priceline.com customers will pay less for their airline tickets than they would at any other major online travel reservation service, including Expedia, Travelocity, Orbitz and Cheap Tickets.

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. Combining airlines can improve itineraries and savings, which is why approximately 20% of priceline.com?s retail tickets now sold include two carriers. Even smaller so-called ?screen-scrapers? like Kayak and Sidestep only offer this feature with a booking fee attached. 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 and up to 30% on rental cars compared to published prices found on major online travel reservation services.

?Since this sale is good for last minute and advance purchase tickets, it will appeal to many different types of customers,? said Mark Koehler, priceline.com?s Senior Vice President, Airline Ticketing. ?Travelers can use this sale to lower the cost of their upcoming summer vacation. They can purchase tickets for a fall getaway once the crowds thin out. Or, consumers who like planning ahead can buy their Thanksgiving and Christmas airline tickets now and lock in the additional savings.?

Recently, priceline.com launched a new marketing campaign, titled ?The Negotiator,? that focuses on priceline.com?s ability to deliver the best deals for its customers. Priceline.com?s airline ticketing service accomplishes that goal in several ways. Using priceline.com?s TripFilter? advanced search technology, customers can:

- Search easy-to-use grids that compare different airlines, routes, flight times and prices. The grid can be adjusted to search by price, trip duration, departure or arrival time.
- Purchase round-trip, one-way or multi-destination tickets.
- Choose economy/coach, business class or first class tickets.
- See sample deals updated daily to more than 60 U.S. destinations and 70 international destinations.
- Search for alternative travel dates and/or alternate airports, which can increase the chances of finding a great deal.
- Check priceline.com?s PriceBreakers service. PriceBreakers is a free service where specially priced last-minute deals are hand-picked and displayed while they?re still available.
- Use priceline.com?s "Name Your Own Price" airline tickets option and save up to 40% compared to published ticket prices.

Priceline.com also has a ?Price Drop? feature lets customers know when a fare has dropped by at least 15% in the past week as compared to the average of the lowest fares found on priceline.com on each of the last 30 days for that same origin and destination. In addition to browsing price drops on priceline.com?s Web site, customers can register to receive e-mails with price drop and other air deals from their favorite city. If a fare is getting close to selling out, priceline.com will post an alert next to the fare.

Priceline.com?s Summer Flights Sale applies only to published-price itineraries where travelers pick their exact carrier, flight times, routes and price. The sale does not apply to priceline.com?s Name Your Own Price service, where consumers already can save up to 40% over the published prices found on major online travel reservation sites.
