Cheap Flights from Baltimore to Denver Starting at $78

Baltimore/Washington Thurgood Marshall Airport (BWI) serves as the region’s mid-size international gateway and is often favored for budget and full-service carriers alike, including Southwest, American and Delta on many domestic and some international routes. It’s located about 10–12 miles south of downtown Baltimore, with travel times to the city center typically 20–40 minutes by taxi or rideshare and 30–50 minutes by commuter train (MARC or Amtrak) from nearby stations; shuttle buses and local light rail connect for lower fares. Fares can often be more competitive than nearby Washington-area airports, but peak traffic and security lines can add time; overall BWI balances convenience and cost, with solid ground-transport links but variable wait times at busy periods.
