I'm surprised many of you are getting advanced notifications!
Just got off with the Gold line and found out that the EUA hasn't yet run on my Saturday flight from BNA-MSP (continuing on to HNL), with R class availability! The agent checked the history of the flight's EUA (whatever that means).
Is this possible? We're less than 72 hours out from flight time now with 4/16 seats occupied on this A319 (apparently, more Airbii are shipping over to Nashville). I always thought the EUA ran in the late afternoon or evening of the night it's supposed to run. I guess this just reconfirms that there's no rhyme or reason to the workings of the elusive EUA.
