YUL-FRA on may 1. What are the odds of getting an upgrade?
Hi,
on May 1 I'm flying YUL FRA and I'm booked in H. Since I am prestige now, I'd like to use a SWU. What is the chance that I'll be upgraded (ie. that one day before the flight there is at least one seat left in I)? Should I call at midnight and request the upgrade?
thanks
