Where did "no FMS" come from? The Piaggio I and II has FMS.
I'm 6'4" and yes, it's tight. But not so bad as I'm gonna quit. I do fine for 2.5 hours or so and then am happy to get out and stretch my legs.
If you compare ANY regional to Avantair then the regional loses big time. "Usually have AROUND 15 days off a month" is a long way from ALWAYS have 15 or 16 (depending on the length of the month) days off. Look, it's 7 on and 7 off. Over and over for ever. You can bid to change your start day when ever you want. Per diem is $2.00 per hour. Over time is 1.5 your daily rate and you only get that if you elect to work overtime (Very seldom you could get stuck in the middle of nowhere and be forced to work overtime because they can't get a replacement for you. It's happened to me only once or twice in the two years I've been here).
You commute on your days on, not off like a regional or major for that matter. There's no "hub and spoke" system. You can fly to JFK and D69 in the same day. You never know where you might end up and I think that's cool. There is no TSA except to airline to your plane at the start of the tour and airline home at the end. When I stand there with my bag open getting wanded down in uniform I think, "job security"! The bigger the pain in the a@@ the better in my opinion.
We stay at much nicer hotels. I was a Diamond member at Hilton within 5 months. Oh yeah, we keep all hotel points and airline miles. That's a big perk as airline mile redemption's aren't "Space A" like your travel benefits. When I want to go with the family I just go and don't worry about sitting around hoping to get on a flight all day...flight after flight.
All I can say is I was happy at my regional (ACA) but that was before I knew fractional flying. I like this MUCH MUCH more. It might not be for everyone but I like it lots.
Fly Safe.
