Depends on the broker, some will pay you, and pay you on time, regardless of what the cr@p airline does. Others (the majority unfortunately) don't have the foresight/balls to ask the airline for the money in advance, so if they ain't paid, toi non plus.
If there is a clause in the contract stating "if the airline does not pay us we are not responsible Bla Bla Bla", well, don't say they didn't warn you. Tread carefully.
