How to get from downtown greyhound bus terminal to BWI airport by public transportation?
Unfortunately they put the Greyhound Station where it is not well served by public transportation. The greyhound station is about a 3/4 mile walk (south of stadium). You need to get to the nearest light rail stop at Hamburg Street station (which is near the football stadium). From Hamburg Street you can take the light rail to BWI airport. I don’t know if there is a shuttle bus. Maybe you can call them? I think you will have to walk the distance.
