Didn't get what I didn't want...which is about all I can ask for!
The thing is, with any seniority bid system, I am not going to get a roster full of LA trips(middle also), so if you bid sensibly, then it can(mostly) work for you.
The most amazing thing for me was bidding for two separate days off, and actually getting BOTH, instead of having a trip over the top of them!
Hope everyone did ok....
