|Things have changed somewhat Valleyboy...
-Rotational travel is NOT standby travel (all tickets are confirmed)
-For the most part, your rotation is your rotation. Yes, sometimes flexibility is asked of you...but it goes both ways.
-Once you arrive in YZF (from your travel to start your rotation), you're given 9 hours to rest prior to going 'on-call'.
-depending on what you work out with them, some guys work 12 days, plus one day of travel on each end, then get 14 days off. If you did work 14 days, plus one day of travel on each end, with 12 days off- you'd be a tad richer as they pay a daily rate (and deadhead days are included).
Like Valleyboy said, I also enjoyed my time there. Good people, the brand new 250's we're great to fly, and although the medevac world isn't for everyone- it's a great spot to work (the Company). Definitely is best to live in YZF...but some prefer the rotational life. YZF-based crews work 8 on, 4 off; plus are paid a Northern-living allowance. Crews are relatively busy, with YZF-based crews flying about 500/year. Rotational guys would be a bit less I imagine.
PM if you have any other questions!
