I'm Gold, so the window for my upgrade is suppossed to open at the 72 hour mark. Sometimes I'm upgraded at that point, sometimes it's at the 48hour or 24hour mark.

For my upcoming EWR-LAS trip, the outbound upgrade email came right at the 72hour (- 2 minutes for processing) mark.

I just woke up to find my EUA upgrade email for the return segment in my inbox. It was sent at 2:11am. That's over 92 hours before my scheduled flight.

Glitch? or are they just being proactive on a light FC flight (it's on a 757-300 with 24 FC seats)
Either way I'm happy. ^
