Ok - I'm obviously very very stupid as I cannot for the life of me see how you book this route? I thought I'd cracked it then I found they'd routed me to Dub then back to LHR then NYC. Sigh.

PS The clinic thread is confusing me….. I don't want to miss a leg? Just fly LHR-DUB-JFK then JFK-DUB-LHR

Or is this not possible?
