Nick1012, read about the partner airlines through their websites and maybe wikipedia or the like. also do a google news search on them for recent events. a broad idea of airline industry events/strategies is also good, try flightglobal.com
i heard they sometime get a bit technical if you claim to have a background in aviation, like a ppl. maybe refresh your knowledge if so.
a guy on my phase 3 was asked in quite a detail what is a day like for a pilot on duty - i.e., when you show up for work, when you go see the dispatcher, etc. etc.
