Looked like the EDI sector was the problem.
When I look at a one way UuA into CW (LHR-IAD) it quotes me 10000 Avios and £1250. I take the price is the same for a return? I'm looking at doing EDI-IAD then a week later JFK-EDI. If I book two separate one ways surely it won't give me the discount..I take i'll have to call for the Avios multicity??
