I suspect folks will be lined up if my recent experience on a DL
764 is a good comparison. Unfortunately, there is one less lav on the Version 2 of UA
's 764 so the Y class passenger-to-lav ratio is actually 68 to 1 in comparison to DL
's 51 to 1 which has 4 lav's for Y class. Business Class ratio the same with UA
with 2 lav's and like seating capacity.
F/A's restrict the use of the 2 lav's at the door 2 location as they are reserved exclusively for Business passengers and as observed.....their own use. A curtain with a sign that read "Reserved for Business Elite" was an attempt, along with an announcement, that lavatory use is restricted to your specific cabin. The F/A's spent a lot of time "policing" the use of the BE
lav's by Y passengers who ignored the announcement and curtain sign. If caught, they sent them back to a Y lav location. If these 2 lav's were occupied, business class passengers had to stand in the galley area or return to their seats. I suspect DL
has a stated policy to F/A's to keep these lav's reserved for BE
cabin use only to prevent so many lining up in the aisle or mid-cabin galley area and to minimize complaints from BE
It was a 9+ hour TATL flight both ways and folks were lined up at the mid-cabin emergency door lav locatin and the lav's located in the rear of Y. Although an announcement was also made that "due to FAA regulations standing in the aisles is not permitted due to security reasons" most passengers had no choice and F/A's ignored the line up. It was probably unpleasant for those seated near lav's to constantly have someone standing by their seat.
So on UA
I suspect there will be no issue for those traveling in Business. Y class will be another story.....so pick your seat carefully and don't hold out to the last minute to go relieve yourself as your standing wait may intensify your urge.
watch what you want. you may get it.
