Nigelondraft is not quite right in his understanding of our P&P process. DEP's cannot be put onto LH fleets ahead of successful internal bidders, the only time this can occur is for pilots that have successfully bid for a fleet change but are still in their first 5 years of service which means BA can ignore their bid. Basically it means that you will be able to move to any LH fleet after 5 years.
737 LGW work is fairly similar to LHR work but with a lot less nightstops.
Roster wise you will not get much choice to start with but will generally get at least one weekend off a month. However the best thing is that once published your roster can't be changed. Heaven if you've come from less stable operations. Nobody is junior for long.....not that it feels that way at the time.
Pay is the best it has ever been for new joiners. Last years pay restructuring meant that new joinewrs have won big time at the expense of the more Senior FO's on LH.
Working out of LHR is a pain in the arse........roll on T5.
