As a BD *G who flies a few times a year via ORD and onwards on UA, plus upcoming trips to LHR-IAD and an LAX-LHR I would happily invest in E+ access. Having read the thread and then the link to the above thread, I thought I'd give it a go and have just telephone UA reservations in the UK.

Their view is that basically that you *can* utilise the method in the above linked thread, but that typically there have been errors and miles posting incorrectly to UA that then cannot be transferred to another program. They advised me to either move full time to UA, or stick with BD and NOT buy access. I appreciated their honesty at least. The agent also put a note in my PNR for LAX-LHR to bump me to E+ if it is available.

Not the answer I was hoping for, but good service from them at least. ^
