ah makes sense now
So it's 14 days before departure, that we get given the option to select seats? I think this is the first time i've made a booking so far in advance!
Correct. Whilst DJ's fleet is growing and expanding (and shifting and changing etc etc) they're limiting online seat selection to be at T-14 days. Until then, you won't know what a/c you're on. Hopefully the new GDS will assist with this too. I'm waiting myself as I have some flights on the 330 coming up as well in J, and after having flown in both configs, i'm crossing everything to get the new (it really is awesome).
