That is great to know (and AF-coded flights for sure that is so, as I've flown on JL flights that I booked using DL SM as AF coded). Is it that for other airlines if the flight is not operated by the same airline as it's coded, even if it's available, DL won't let you book it? Or just that other airlines (other than AF) will not release into award inventory flights operated by others under their code? Just curious..
