I had three bags because I was told that I could carry on two and check up to three. Well, it turns out that I could only carry on two....they only check bags to Downtown Baltimore not BWI Rail Station which is where I was going. Then my train didn't get to the station until almost an hour later than it was supposed to. The A/C on the train was broken and it didn't actually get to Baltimore until 2 1/2 hours after it was supposed to. By that time, I was hot and tired....Luckily, my flight the next day went much more smoothly (other than turbulence) and I slept most of the way.
