Baltimore-Washington International Thurgood Marshall Airport already saw several delays and cancellations Monday as one of the busiest travel seasons of the year gets underway. “Our flight was at 12:55 p.m., then they changed it to 9:05 a.m., now they changed it back to 3:55 p.m.,” traveler Tammy Bowers said. Many of the delays and cancellations can likely be attributed to Sunday’s stormy weather in Maryland. As heavy rain and stronger winds hit New York, travel troubles piled up for passengers heading north.
