Upgrading on Egytair with cash or Star Alliance miles?
My mother is taking Egyptair from the US to the Middle East next year. I assume that she just bought a regular coach ticket, as inexpensive as possible, as part of a group that's going on a trip.
Can she upgrade, either in advance or at the airport, by paying cash?
Otherwise, can my US Airways or United miles be used to upgrade her? I'm Star Gold (Gold Preferred on US Airways).
Thanks!
