To waitlist SQ flight, I need to have the appropriate mileage in my account ?
I found the answer, after searching, that I need it.
Question is, if I waitlist SQ, FRA-NYC, after the miles post, and then go ahead and book LH, TLV-FRA-NYC F, for 75K miles, leaving my account with zero miles, will the waitlist expire, or will it stay, and if it clears, I can call them to change it, and just pay the change fee ?
