Go to SKYWEST if you want ORD. Up-grades at SKYWEST are 1.5 years and they have growth. Last bid at AE was 7.5 years on Saab LAX and 9.5 years on the ERJ ORD. Even if every flowback goes this year, (which they will not, maybe 180 will go), the upgrade will only drop by 1 year maybe 2 years at most.

PS I forgot to metion they clxd the last upgrade class on the Saab...
