Hello, I am ok with a late Thursday and early Monday (I have already added these days in as essentially "throw away" travel days... i.e. I only need to be in NYC Fri-Sun). I would like to get the price for this flight below $300 if possible, and absolutely no more than 350 (otherwise I would rather choose the exact flights). Any and all advice would be greatly appreciated. Thanks!

Looking for a flight from Spokane (GEG) to the New York area (either JFK, LGA, or EWR). Flight dates: Depart 7/28 (Thursday) and return 8/1 (Monday) Best price I could find was $398 + $46 tax ($438 total) on Alaska Air. Other comparable flights hover around the same $450 price range (including taxes). I have done many Priceline bids on hotels but never on flights, so I'm looking for some advice of how to get the best price. Thanks!
