Interesting, just a couple of things:
1) Will there be seats facing backwards? Or is the configuration going to be 6 across? Cos the seat width of 25" is very, very wide...
2) Hong Kong will get them because they're fighting the CX product, and of course, the BA product.
3) Look out SQ!!!
I don't think they will install them onto the 744ER's yet cos they will mostly stay on the Pacific routes because of their greater load-carrying capabilities. Since UA don't have a 'bed for business' yet, why bother on that route?
