Have never used Priceline. Seems too iffy on times and price. Used Hotwire once and was satisfied with price and service. However, we had a stopover and I'd rather go nonstop. Also used Orbitz. Price and service was fine but didn't like the service fee. You also can't make changes once you buy the tickets. We're heading to Vegas on April 22. Bought tickets two months ago directly from Continental's web site and got a better price than on Orbitz with no service charge. However, leaving on a Sunday might make your tickets a bit more expensive. Not sure what airline serves your area but it might be worth it to go to their site.
