Tips on getting the best Seattle airfare

If you're interested in getting the cheapest tickets to Seattle, consider going during the low season months of November through April. Although it does rain throughout the year, the majority of the rain occurs during the fall and winter. Due to the rain, you'll find great prices on hotels and discounts on many attractions. High season is from May to October; you'll pay more for tickets, but you'll get to attend some of the numerous festivals going on during those months. If you want to save money on your tickets, try booking them as early as possible; tickets tend to get more expensive as the departure date nears. However, another tactic is to get tickets at the very last minute; if an airport hasn't been able to sell all the tickets on a particular flight, oftentimes, it will release those leftover tickets at a shockingly low price, but you'll have to move fast in order to snatch those tickets up in time.
