Hockey East teams rarely get on a plane because they don't need to do so. Nearly the entirety of three conferences (HE, ECAC, AH) is within a 10 hour radius of Boston. In looking at their member team schedules the last couple seasons (not even considering 2020-21 as no one traveled) I would say a very generous average would be 0.5 road trips that require a flight per season, per team. (I did not consider Notre Dame in that number as they were a conference member.) Meaning about once every two years a Hockey East team takes a non-conference road trip that requires a plane (that isn't the NCAA tournament). A long road trip for a Hockey East team is nine hours, and that is if the bus breaks down for four of those hours. From what I remember U-Conn to Maine was the worst trip in Hockey East and that was about a 5 hour drive.
A lot of trips for Western teams, 5 hours is the first rest stop, then back on the bus. In looking at the WCHA, and I'm going to even ignore UAH and the Alaska schools and just look at bus trips, by comparison, the worst WCHA road trip is Bemidji - Bowling Green which is 14 hours. Then throw the three UA_ schools back in the mix and you start to understand why the CCHA is reforming. The WCHA v2.0 was unsustainable from a travel standpoint.
You first said BC. I haven't studied other schedules but BC has traveled west a lot to play a lot of different teams.
