Its better if 2 feds are going the same route split it, but thats no always the case, onwhich to me is very stupid, as cutting the cost is better. Only the small amount owe guys willing to go oot there way ti help though.
The decision has been made to fly the West route, you have just got to get on with it for a season, if it dosent work out, then change it next year Simples. All the best for the guys flying the West route in 2012.
