Just speaking for my case... I was on reserve for 2 weeks (ORF based). That was in the May/June timeframe. I have been a line holder for 5 months now, the senior guys in my class will get a line from this last bid in DCA and guys in my class in PHL are still going to be 5 from holding a line. Don't really know anything about LGA.

As far as Airport Reserve goes, I intentionally bid that for a month and it worked out great, I'm thinking of bidding it every 3rd or 4th month just to give me more time with the family (home 90% plus of the nights). Of course, if you commute, it may not be the best choice for you....
