(some of us remember the old quick-progress specific domestic side of Terminal 1)
Goodness me I forgot about that old route, whilst it used to queue quite a bit it always moved quickly and the staff were always very friendly.
Assume it was the fact that the passengers were regulars and knew what they were doing.
Always liked the old BMI lounge; filled my pockets with Lindt chocolates to give the family when I got home!
