US low-cost airline Spirit has a sale on flights from Washington D.C. to Seattle for as low as $93 return! That works out to a cost of just 2 Cents Per Mile flown for this 4,600 mile journey.
Since this is a low-cost airline, only a small carry-on bag is included, and you will need to pay extra to bring a carry-on trolley or to check bags. If you have lots of luggage, those fees can end up costing more than the original flight price.
