I came from an LCC where I had to deal with a base closure out of nowhere; by way of an unsigned memo... (totally over it by now...) Then the subsequent bases I was at for the rest of the year were cut by 1/3 each quarter. Also flew with a 6 year captain at said LCC who was in my BI class. Got the base and aircraft I wanted straight from the gate at United. There is no perfect company, but the grass is greener for me. We also had a 60 year old in our BI class if that helps anyone. Which leads me to my advice that has been echoed by others, if you have 10+ years left and less than 5 years-ish at an LCC, I would make the jump. There are unfilled CPT positions, and as of right now it is not unreasonable to expect a CPT position (depending on fleet of course) within a 1.5 - 2 years, if not sooner. Good luck on your decision!
