Yep, understand that just fine too. What I'm getting at is that PBS is about efficiency. Due to the drastic reduction in open time because it avoids conflicts, the availability of trips to trade with greatly reduces. What I was saying before was that the availability to trade for those 2 days just simply may not be there.
The 2 day trips will be there and will be awarded in seniority order via PBS. All of those golden trips that senior crewmembers get and then have dropped due to conflict at XJT will be awarded at ASA via PBS because the senior crewmember can't bid on any conflicting pairings. So really, many people won't have to trade trips after schedules come out because they will have been awarded the trips they really want by PBS.
