What time of day does the calendar move to the next day (booking 330 days out)?
I know this is an awkwardly worded title (Mods, please feel free to change it to something better).
Using Expertflyer (and looking at Aeroplan), I had my eyes on award space on a Star Alliance partner flight from Europe to the US for next July. Because United won't let you book as far ahead as Expertflyer can see, I was waiting for the magic 330 day mark to use my United miles. The last time I checked last night, the award space was still available on EF and Aeroplan, and United.com still couldn't "reach" the date. This morning, when United.com could "reach" the date, the award space was gone. I now realize I should have stayed awake until United.com opened up that day for booking.
Does anyone have experience with what time of day (is it midnight Central time, etc.?) United rolls over the 330 day mark to make that next day bookable?
Thanks!
