Upgrade times are always changing, but current upgrade times can at least provide a snapshot. Out of morbid curiosity, how long was it before the most junior Captain upgraded at:
1. Delta
2. American
3. United
4. SWA
5. JetBlue
6. Spirit
7. FedEx
8. UPS
9. Alaska
10. Hawaiian
Would be interesting to see this graphed. DOH / Date of first upgrade opportunity
