Hi there.

Anyone know the cost in both $$$ and miles to upgrade from E+ to BusFirst IAD to LHR in T vs W?

Is there any appreciable difference?

Basically, I can pay for this ticket in GBP £2125 in T OR $3808 in W.

£2125 = $3600 per the exchange rate I need to use.

That said, the plan is to possibly upgrade from E+ to businessfirst on the return. So, if it's going to be $500 to upgrade from T vs $50 from W, I am better off with the W ticket, even though it's more expensive on its face.

Anyone know T vs W costs to upgrade?
