If no United status, the check in line was long. We had checked in online but they needed to verify our negative COVID tests for the destination even though they were in thr app. Even with the long line, 2 hours is plenty
Agree-- if you can get your boarding passes by preloading your passport it's just a question of how quickly you can check your bags and get through security, and status and pre-check help with those. I think 90-120 mins would be ok especially if you are not flying at peak (for Dulles) hours (which I think is mostly the late afternoon?)
