The lack of terminal facilities didn't seem to hurt DJ in their early (and then not so early!) days of operation. I remember dropping mates off & seeing people lined up in the rain outside the tin shed there in Sydney. Not to forget the tent circus that was set up as their terminal in newcastle. I believe Adelaide travellers were also treated to a 'basic' style of terminal building. But look at the end result - it didn't seem to mater as long as the fares were cheap...
I'm guessing that in 12 months time much the same will be true for J* as well. It will be interesting to see how long DJ can match the J* low fares & still maintain/make a profit (especially with the new disclosure rules that they must meet as a publicly owned company). Especially in light of the rumours as to just how close they came to the wall last time there was a real air-fare war...
