Notsofast,
In the past, First Fly guys were assigned trips, not standbys. It there weren't enough trips for first fly guys and there were still some standbys left over, the standbys would be assigned to the person with the lowest leveling. They have just recently been assigning standbys to first fly guys. I will never bid first fly as a result.
This change of policy doesn't really help the company (they don't care about leveling order other than to abide by the contract, all they want is a warm body in a seat). It just makes first fly less desireable for some of us.
In your case, obviously if everyone was on first fly, they would have to dole out the standby in leveling order. I still think they would pick the first person with 2 days of availability. I am not sure that doing this is legal by the CBA. Trips less than 48 hours TAFB should be assigned in leveling order. Are they treating standbys as trips????
Anyway, r1200, I would contact contract enforcement. Historically, I haven't seen standbys going to First Fly guys unless they would get assigned one anyway due to leveling order. I don't think this would be hard to get fixed, since it doesn't seem to really benefit the company.
