Pleasantly surprised today on YYZ-LAS. I was second on the upg list and the flight checked in full. I boarded in Zone 1, was seated for about 15 mins and the plane was halhway thru boarding when I got a text that my upgrade cleared. Asked the FA to check with the GA and after boarding was almost complete, got a new BP and moved up to J. I guess there were misconnects. No idea if No 1 on the list also got upgraded.
So despite me boarding, I guess the list was still active ?
