like said above... While it can do it and there was SEA-IAD, it's highly unlikely unless it's a new route. I came from 220. Long skinny routes. Lots of Texas. Boston. Chicago. Etc. Those markets. I wouldn't say the trips are going to be that fun, lot of business flying. Not much regional flying or small airport flying....despite everyone thinking it's a regional jet. The seat configuration layout was designed for more premium seats. It's used on skinny business premium routes for that reason.
