Boeing have introduced a new naming system with their newest models - 'Dreamliner', 'Worldliner', 'Incontenental'. Even Airbus has started it with 'Xtra Wide Body'.
How about giving the 737 & other 777s names? I think 'Cityliner' would be a good one for the 737. I also think they should extend 'Worldliner' to the whole 777 range, and maybe 'Freightliner' for the Freighters. Any thoughts on this?
