Hi regarding promotions, well i have done a lot before. You shoud have first BP day on which you will go to the office and they will tell you all details. Who ever called you up to inform you you where doing BP should have told you what time is you BP meeting. On which you will get your ticket etc... thats if its overseas.
As regards to Air Wing i think you can be married and you can apply when they advertise on portal to you CCS. I dont think they are recruting at the moment. You cant be SFS or PUR to apply.
Good luck !!!
