One thing I always wondered is if it is considered faux pas to cross fromY into J/F to use the washroom consider these scenarios:

• E+ with UA Gold sitting in bulkhead (behind F cabin) on a UX flight (i.e. DEN - YVR)
• E+ with UA Gold sitting in emergency exit row towards middle/end of cabin on UX flight when back washroom is in use
• First two scenarios except on international long haul itinerary (i.e. EWR -> ZRH)
• Above scenarios with super-elite status (i.e. 1K or Global Services)
• Above scenarios as a kettle

I don't suspect the first two are faux pas on account that I could have easily been upgraded into F via CPU if luck was on my side.

Would be interested in getting fellow FTers opinions on these scenarios.

Safe Travels,

James
