Okay, call the airline and ask them how much it will cost to send the extra stuff, they may not even allow you to do that. There are shipping companies that will take part shipments, ie they will put your stuff in ith someone else's (hey guys anyone else out there moving around the same time that want to share a shipment)? Basically they could care less whether you are going to live in Belize or Heaven they just want there money, sometimes you get lucky and the person checking your bags thinks your cute and you get a bit further, but they have tightened up everywhere now. No more bribing (rotten habit anyway, but used to be used a great deal). Clear your mind, you've enough to worry about moving so just ask, they you know.
All the best.
