After looking at the seating layout for the upcoming A321XLR fleet, the restroom-to-passenger ratio in economy seems surprisingly limited for a full-service airline.
Based on the configuration, it appears that roughly ninety economy passengers could end up sharing a single rear lavatory. That seems less favorable than what some low-cost carriers provide.
For longer domestic routes, particularly around four hours in length, I can imagine restroom lines becoming a noticeable issue once the cabin is full.
I’m curious whether others see this as a concern or if I’m overestimating how much impact it will have on the passenger experience.
