While not a credit record, here is one I'm proud of from my first officer days:

94 hours credit
0 block

How? Bid with a checkairman, displaced the entire month, never reassigned.

102 or 103 credit
0 block

reserve capt in jan at colgan with a pc moved twice onto days off due to wx.

boom !

2 day trip, 10 hours block, 38 hours credit (after incentive, premium, and JA), which by itself made for 113 credit on my reserve line. But it started on Christmas Day at noon, back when scheduling was doing stupid incentives (e.g. 8 hours credit for 3.5 hour turn).

When we used to have charter we had guys double dipping and crediting well into the 200s in a single month while only crediting in the mid 90s. Those were the days! We also had guys doing this who were TDYed to the west coast and agreeing to deadhead on their days off. Must be a lot to pay uncle sam!

138 credit 85 block. Current Pinnacle contract. I kept getting bought off my trip and I picked up at 200%

118 hours at 200% pay plus
62 hours plus
462 hours per diem

So in actual numbers - 298 hours credit
73:35 block

I enjoyed that check until I saw how much Uncle Sam's cut was....

All this was made possible by rolled days, restored days, dropping flying that was picked up at 200%, picking up more flying at 200% on top of that, legality issues, lots of deadheading and a lot of luck.

By bidding long call as a senior pilot at Comair in 2009, I was able to credit 225 hours (3 months gaurantee) while only working 1 leg for a total block of 1.8 hours! I win!

Credit: 200+
Block: 0-50.
When: Every month
Who: Certain ALPA leadership on fulltime buy.

140.2 Credit, 99.5 Block. Thought I rocked it but apparently y'all are pretty good!
