... well ... to ge honest ... a slight exaggeration. We (UAL) bought our first Airbus' in 1993, so it's actually been 23 years. We were quite literally shocked when we heard the official announcement at a basewide meeting in SFO's Dock 1. I took the liberty of skipping the actual math when I posted.
As of September I work on a scheduled drop-in line so I don't work on A319/A320 exclusively anymore.
