Here's what I find is the most difficult about FAR 117, it's harder to bid. Yep, that's right, because of the moving time periods I end up having more time off than in the past. That seems to be only bad for those who want to work more. Frankly as an international pilot I have never exceeded 86 hours pay and normally get about 80-83 with 18 days off.
Before 117 I could group trips, fly the same trip three weeks in a row or more. Now I'm forced to have a week off between trips at times and very few trips can be flown back to back.
Yea, it makes bidding more difficult.
