My last taxi to Baltimore from Dulles Airport was $135, with no tip added yet. It was late at night with no traffic, so that helped with the price. It could be much closer to $200 with traffic during the day. I would have flown into Baltimore International, but the company was paying and that was the way they wanted me to travel.
It's about an hour and a half drive. So a taxi would be kinda expensive. As someone else suggested, use lyft or uber.
Probably cheaper
If you have the Uber or Lyft app try those maybe cheaper
