Just a followup to this i get in early AM (6am) and was hoping to have a shower, i'll be in the domestic UA terminal. I have been told there are no showers either at UA or AC departures in domestic, further the only showers available for free would be the UA RCC arrivals but that's only for F and C pax... any way I can convince them to let me in here, i will be flying in Y, and have an outgoing ticket later that day (evening) on UA...
