Cheap flight home after Space closing??



I have won a holiday to Ibiza on 24th September. Basically I can't get the whole week off work so Im trying to get a flight home on the Monday after Space closing but don't know how to get a cheap one? Anyone have any ideas? OR.. :rolleyes: :rolleyes: 8) if anyone is out there and is going home on the Monday 29th & wants to stay til the Wednesday & wants our accomodation & wants to swap flights then let me know!! I know its a long shot but I have to ask!!! :rolleyes:
Wish I could, would get the sack though. Unless anyone can come up with the best ever excuse to be off work as they will be expecing it! :cry:
Try Most flights seem to be around £50-£60
