It takes roughly six hours to fly non-stop between east and west coasts. Flights running north and south between coastal cities, such as routes between LA and San Francisco, take anywhere from one to four hours. Aggregator websites for discounted airfares are an easy way to simultaneously search several airlines for their best prices. Some, such as Momondo and Kayak, act as search engines just to review prices. Online travel agencies such as Orbitz, Travelocity, and Expedia let you compare costs and book tickets directly.
