I admit it. I am not a morning person. A 9am flight is enough to change me from Affable Annie to Grumpy Gert. So the thought of having to be at DEN at 5am for a 9am flight is not a happy one for me. Arriving and finding out the counter or the Red Carpet Club won't be open for another hour or so (as others have found) would turn me into Ms. Hyde. So to protect fellow travelers I have contacted United to find out counter hours and RCC hours for two upcoming early flights. I thought this might be useful info to post and invite others to do the same.

DEN
United Counter opens at 4:45am
RCC East: 8am-7pm, closed Saturday
RCC West: 5:45am-10pm

SNA
United Counter opens at 5:00am
RCC: M-F 5:30am-7pm, Sat 5:30am-2pm, Sun 7am-7pm

NOTE: These times are probably only as firm as the flight schedules, so don't be surprised if they change.
