I've done the APC for Abu Dhabi center. They paid for most of the expenses. Airfare/hotel/breakfast/transfers to the center.
Honestly I didn't mind the APC itself. It was a day and a half of classroom and 3.5 days of SIM where they just keep bumping up the traffic to see how you do. Its pretty busy by the end and you end up with stacked holds up to about FL200. I guess I "passed" it, whatever that means, since I have been offered a training position. Supposed to start in January if I want it, but now struggling with the decision.
Love the idea of the adventure, but like the stability I have here in Canada.....
