I am JB, still fly with the reserves. Actually deployed right now.
Advice:
1) Don't bring any attitudes to training. You may be much more cool than your peers, you just don't have to tell them you are. You have lots to learn.
2) Respect the civvie dudes. While you have probably done more interesting and demanding flying, they own part 121/135. They are good pilots, they know their sheet, and they probably have lots of flt time/experience/multiple airlines under their belt.
3) Find out the dork in the class and distance yourself from him.
4) Bring a vehicle. Use it to invite the FAs in training to the Orlando Ale Haus. Every night.
5) Invite the FAs to your class party.
6) Believe 40% of the koolaid. No more, maybe even less. Time to build your defenses up.
7) Never refuse a breath mint. But that works pretty much wherever you go.
8) Don't crack a "book" (actually, CPAT) for the first 7 days. I recommend you do the OSC pub crawl: Chilis, Bennigans, TGIFridays, Hooters over and over again.
9) Bring lots of cash to Rachel's. The ATM fee is 10 bucks a withdrawal.
10) Go to the Rennaissance bar on Sundays. Either Virgin or BA 747 crews there (admittedly dated, they may have since moved), meaning lots of government sponsored health care b00b jobs. Sometimes even the female stews have them.
11) Register with the JBPA and take part in your future.
12) Remember: some on this forum would have you believe that is is dishonorable and shameful to fly french/brazilian airplanes, not to mention work for JetBlue. So to speed up your self-loathing process, I recommend that you do numbers 4,8,9 and 10 often and early.
13) Don't PM me for more advice.
not sure if any of this helps. good luck and welcome. bring sarcasm and plenty of underwear -- you'll be thankful you did.
