I will arrive at IAD from Tampa at concourse D at 4:05 p.m. I need to get to concourse B to catch the SAS flight to Copenhagen at 5:15 p.m. What is the best way to travel between the two concourses? The luggage is checked through, so we won't be lugging anything. Do we walk, take the AeroTrain or Mobil Lounge shuttle? Which is most efficient (in case thunderstorms force us to rush)?
