Looking for a cheap flight from Baltimore to St. Thomas? This page tracks the lowest fares we have recorded on the BWI to STT route, the airlines that fly it, and the months when prices drop. Fares shown are recent lows, not live quotes; call (708) 866-8751 and an agent will price today's availability with you.

Delta Air Lines and United Airlines both operate hubs at one end of this route, so nonstop or single-connection service is usually available, along with American Airlines and Southwest Airlines. Our agents can book any of them and compare fare classes side by side.
1,601 miles is a serious flight, roughly 3h 40m nonstop, and it is the range where premium economy or a domestic first-class seat can be worth asking about, particularly on midweek departures when upgrade fares drop.
Winter fares out of the Northeast peak around the holidays and February school breaks; late April to early June and September to early November are usually the calmest on price.
Midweek travel almost always beats weekends on price here. If your dates are flexible by a day or two, tell the agent; shifting a Friday departure to Thursday or a Sunday return to Monday is the single most reliable way to cut the fare.
For domestic travel, booking three to eight weeks ahead usually captures the best price. Inside two weeks, fares climb; more than four months out, airlines have not yet released their cheapest inventory.
