Had my first experience travelling on a regional airline from the new Adelaide terminal. It would seem that when they designed the new terminal they forgot about the regional air passengers. The departure "gates" for both the regional airlines are situated at the extreme end of the terminal requiring a fair walk although you can enjoy for part of the way a 50metre travelator (though not sure it works). When boarding you have to be escorted by the flight crew down a number of stairs to the exit for boarding. Regional air passengers returning to Adelaide airport again have to be escorted by the co-pilot to the terminal building through a concrete passageway then go through airport security and return to the upper level departure area through a door that is well away from the designated arrival area shown on the monitors to depart the terminal. Interstate passengers have to walk down two ramps to the aircraft and it would seem for speedier boarding passengers seated at the rear of the aircraft are directed to walk across the the tarmac to the rear steps of the aircraft. A procedure no different from the old terminal. Adelaide airport had a great opportunity to build a 21st century air terminal it would seem the opportunity was taken up!
