Short answer...no. While it would be great to get a call from an airline this winter, the odds will be very slim. The airlines will just be spinning up hiring and the initial calls will go to those with friends in very high places and then to those with friends in high places. Got any of those? United, although "hiring" now, they really aren't. Those pilots have already been notified and few guys scored big time but the real hiring is starting this winter. Delta, sure in 2014, but they too will take months to really spin up and work through their required regional hiring. FedEx and SWA forget about.
If you retire and you don't get a call you'll wish you had stayed the 6 months. Its a crap shoot. But really we're talking about double digit seniority numbers lost, not triple digits!
Save your leave, tell the airlines spring availability.
Good luck!
