Sorry - and I may be alone here - but for anyone who first travelled long-haul in the 70s and 80s when long haul meant 747s, DC-10s and L1011s, the idea of an XLR A321 feels like yet another retrograde step in aviation, akin to stepping back into the 707s or DC-8s narrowbody long-haul era....
If the 757 taught us anything, it was that long haul and narrow-body really don't mix.... with the possible exception of Donald Trump's Biz-Jet(!)
There has to be a better way!
