If you are not in the top two bid months, then is there any point in actually bidding? Someone at the bottom of your group has just as much chance getting what you want anyway.
I am sure it's more luck than anything but did I get the days off and destinations and even one flight on a specific date that I wanted in July. I did have over 40 lines of bids and it was my second top bid. I therefore find it impossible to comprehend how having significantly less influence on the bidding system will bring better results. As far as I am concerned, it's a disaster on a grand scale that is now slowly unfolding.
