I did the 18 seater BEHs round trip weekly for about a year before I discovered FT. As others have stated, bring earplugs... did I say bring earplugs? Yes it's small. Yes the 18 seaters have lavs (no real soap - just hand sanitizer). No FA. Just the co-pilot making the announcements. The air that shoots through the large a$$ nozzle next to you spews out air temperature air so on hot days, it will be... well... hot. No overhead bins. Seat "underspace" in front of you can barely fit a small laptop bag (anything else would require gate check, no different than other props and even CRJ, per se).

We flew threw a storm cloud once (pilot opted to go through shortest point rather than go around). Now THAT was scary as hell. People cried on board.
