Don't know if I'm too late but check out
www.britanniaairways.com and learn a bit about the history, bases, routes, etc. Thats what I did and when they asked me what I knew about the company I reeled it all off. Must have worked 'cause I got the job.
Was there for 3 seasons, and out of the three airlines I've worked for they were the most enjoyable. Would probably still be there but I packed it in for something less stressful - air traffic control.
Good Luck!
