most passengers are not connecting at MEL.
Who wants to go thru all that BS security at MEL.
Who wants to have to walk miles just to get to the aircraft.
Who wants to have to go past 100 extremely overpriced shops/takeways just to get to your gate.
If you're originating in Melbourne, believe parking, right beside the terminal is still free at MEB.
It's really a no brainer.
No one wants to go to BUA's anymore, ANYWHERE.
