I've just checked my proposed routing and it was WLG_SYD_LAX-ORD-JFK-HKG-MEL-WLG and it was under 26,000 and the agents clearly stated that the problem was the backtracking from going west to east to west again ....
But I"m going to give it another go as i've a similar trip coming up!
Maybe your routing exceeded 26k miles and that is why the agents considered it invalid.[/QUOTE]
