Hi, complete newbie to the forum and getting awards/upgrades here!
Trying to book a return flight LGW-HAV, going out 4th September and back 15th (cutting it fine, I know...). Have earned enough miles to start getting reward flights, but trying to work out what the best way of doing it is?
Want to get an upgrade if I can, especially given the long-haul and overnight return. I know that using miles to upgrade from e.g. M fare to PE and then UC is the best value way, but, er... how do I do that please?
Sorry for the really basic question! Hoping someone can help... thanks in advance!
