EUA Midnitght - What time zone?
Tried to find this info, but I'm probably not a good "searcher". When the NW and CO computers do the EUA at "midnight", is this midnight Eastern time (EWR/DTW), Central time (IAH/MSP), midnight in the time zone where the flight originates, midnight where the passenger resides or some other possibility??
At DL, they used to refer to 24/72 hours before in the timezone of the flight departure.
Thanks in advance....wondering so I can time the call to NW when the CO EUA doesn't process.

The rule is the "day" before, not 24 hours.
CO starts running their EUA at midnight IAH time. It usually takes 2-3 hours for it to complete. From what I've seen, it appears flights are hit in order of absolute time of departure (e.g., 7:00 a.m. out of DEN before 6:01 out of SFO), starting with the 12:xx a.m. redeyes, and ending with the 11:xx p.m. ones.
NW starts their EUAs a few hours earlier than CO. It's not uncommon to get a NW EUA at 6pm-ish Pacific Time, two days prior to departure for a Silver.

NW's EUA actually runs about 12-16 hours before the alloted time... so if you're Silver, you'll know if you've been upgraded (usually) ~36 hours out.

IP: yes, that is also our experience as golds.
We already knew we were upgraded on Tuesday afternoon earlier today (Friday), for example.
May depend on the loads expected for the flight, I would guess.

I was also very surprised (as a Gold) to see my seat upgraded to F late on Friday evening (Japan time) which I guess was very early Friday morning in the US.
I was expecting to go on the standby list - a nice surprise before I went to bed to be confirmed in 3B!!

Lighting candles, praying to the upgrade gods, and obsessively refreshing Galileo and itinerary screens well into the night. I guess you could call that experience.

FWIW, I was upgraded for a flight on 11 Nov. last night (4 Nov. just after local flight departure time) and checked every few minutes. Coincidental or not?
This is the first time I've monitored.
