Have you got to the bottom of why using a UK POS increases the fare by that much? Are the lower economy booking classes unavailable using a UK POS, pushing you up to a higher DIF based on a higher economy booking class?
If so, have you tried looking at other POSs to see whether there's another POS that can replicate the price that you were originally thinking of?
