7 years for Brisbane?? Tell him he's dreamin! Current lot of guys getting melbourne 737 are around 8yrs in the company, as for Brissy...I guess anything is possible around here, but I wouldn't expect a new 737 command there for a very long time. The base will not grow, and those that have commands there sren't likely to let them go!
All depends on the rate of A330 expansion I would say.
