从奥德萨飞往巴尔的摩，马里兰机票含税

When it comes to booking your flights, it's always better to be prepared. While it's possible to find a deal on an ODS to Baltimore Washington Intl. Thurgood Marshall Airport (BWI) flight at the last minute, fares usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to lock in a domestic flight is between 28 – 35 days in advance. For international journeys it's between three and four months.

Thurgood Marshall Airport (BWI) itinerary through the Expedia Trips portal and read the fare conditions to see if you can make changes.
