John, you can take this an put it in the anecdotal evidence file. A while back I caught up with a QF A330 SCC, and he related to me a story about 2 J* Cruise FO's who he had checked the week before. They were both new on type & with low jet experience (no criticism intended). The session didn't go well, in the debrief the SCC told them they would need to repeat the session. One, became quite distressed at hearing this. The SCC explained to him that with study & practice they would make it through. However, the CFO then explained that the repeat would have to be paid for out of their own pockets at the full rate, not J*.
Perhaps someone from j* could confirm or deny that repeats are at the pilots own expense.
