Aegean website won't take our United MP numbers!
Several short flights on Aegean coming up for an August trip. I have purchased two of them already over the past few weeks, no problem entering our United MP numbers when booking.
Trying to book the third flight from ATH-TIR and it keeps saying our United MP numbers are invalid. But they are not invalid, and I have tried several times. Arg. Anyone else having/had this problem?
