For completeness:
A350, 5.96m
A330, 5.64m
Typical flight distance certainly is a factor for DL (and customers' willingness to pay). Cabin width may be a factor in floor space utilization.
I see we're splitting hairs on this lovely tuesday morning. Sorry for glancing at numbers and making generalizations, but the premise stands. The 767 lie flats were a struggle to implement in the first place, and feel like a coffin. Good luck adding doors to that.
