I don't know why anyone at a regional would want them to grow with bigger aircraft. I always had my eye on the ball of moving on at a major and was very fortunate to make that jump in 2007 before Age 65.
I couldn't be happier.
While our contracts need improvement from the post-9/11 era, my worst day at a major beats my best day at a regional.
I think once Age 65 comes to pass you'll see a lot of the cheer leaders for 90-110 seats at the regionals move on....and they'll be saying the same thing in 5 years!
