Looks like a line holder on the E190 is about 6 months. It had been about 1-2 months of rsv 6-12 months ago.
Avg 190 FO rsv this month looks like it will be about 45 hrs. 20% will be above 60 hrs if the current totals are projected through the end of the month.
Rough WAG looks like PHL 320 FO's are flying about 10 hrs more on rsv this month.
The E190 is a good deal BUT the company can keep you in the bid status. You'd get the G2 pay while flying G1 trips. The downside is you're stuck on the E190 vs perhaps bidding a base that has an easier commute (CLT? LAX?).
