I hate to keep beating this issue up but I just looked at the last upgrade award, the latest hiring update and the seniority list. The most junior pilot in next month's upgrade class was hired 11/13. So that's a 26 month upgrade and he was in the 3rd class after no hiring for basically 5 years.
His seniority # is around 620 so with another 80 upgrades for the year you're looking at #700 who was hired in April of 2014 as the most possible junior captain.
We hired 160 in 2014 and another 170 in 2015. Simple math tells you those guys will not upgrade in 2 years.
Having said that. We have grown 50% over the last 2 years. From 630 to about 950 pilots. The Neos will start showing up later this year and I'd imagine 100 upgrades a year for the foreseeable future so it's a good time to come to Frontier. Just don't expect to be a captain in 3 years.
