I am thinking of using miles to upgrade from my PE S fare to a G class reward. Assuming availability, is it possible to upgrade at any time, e.g. even on the day of departure? If there is no availability showing for my chosen dates now, how likely is it that a seat will become available closer to the time (LHR-MIA route, end April).
Also, can I use both the CH and Revivals lounge on this fare type?
Thanks in advance.
