In case it isn't clear enough (and it is)...
Same aircraft, same VAI AOC, same pilots who will fly the 3 repainted aircraft and the other 22 VAI 737s. Very nearly the same schedule.TT cabin crew are trained to VAI standards for EPs etc. Just as VAA cabin crew can operate on VAI 737s the TT cabin crew can operate on both AOCs.
As for what the 3 repainted aircraft do when they're not on those Bali flights I do not know.
