Alright this is starting to get confusing. By marketing block you mean the Cal/Delta/United block times that people see on their ticket right? This SAT stuff is confusing, I understand yall had it at 9E, but does this TA have normal block by leg like most airlines? All this SAT stuff is clouding my understanding of it...
At 9E, when you look on your schedule, there's a "block time" listing, which is your scheduled out and in times. The "leg value" (which to me seems to be the same as SATs in the JCBA) is your "credit," which is normally different than the scheduled block. MOST of the time it varies by minutes. In the winter if you're doing something like DTW-ERI, it's gonna be scheduled longer in order to accomodate de-icing. If it weren't, the flight be would late by DOT rules most of the time. The leg value/SAT doesn't change since it's based off an average of the past year (or 6 months in the new case). So, you're crediting LESS than the scheduled block. Under 9E's current contract, you get hosed unless you fly leg value + 15 minutes, then your clock starts again. The JCBA fixes this issue. If you fly over the SAT (which if you're de-icing is almost a certainty), you get paid whatever you fly over that amount. It may be less than the block in minues the block out time, though.
Example:
Dep Dest Out In Block Credit
DTW ERI 1200 115 1:15 1:00
The above leg would have a block time of 1:15, but the credit would be an hour based off the history of the leg flown on average. If you fly more than an 1:00, you get paid whatever you fly. If you fly 00:50, get paid 1:00. Even our PBS results have different results for scheduled block and credit.
I'm not sure how other airlines do it, but I know that scheduled block times at 9E are historically longer in the winter than in the summer to account for de-icing and winds. Would make sense for it to just be the same scheduled block year round, but like I said, in the winter, it would make most of the flights habitually late except for maybe out of MEM, ATL and IAH. Then they'll just cancel them if they have to de-ice.
