JAL to introduce Premium Economy service on Haneda-Hong Kong route from April 1 2012

According to Japan Airlines (JAL) website, Hong Kong (HKG) will be added as a new destination with premium economy service from April 1 2012. But this only applies to flights to/from Tokyo Haneda (HND), i.e. JL028/029.
JAL has been using its long-haul 3-class configured 777-200ER (configuration W51) on this route since the Haneda internationalization (although sometimes it had occasionally switched to the regional configuration). JAL Mileage Bank and oneworld elites have been enjoying those premium economy seats for free as JAL only provides 2-class service on this route. It's about time they start charging people who want to sit in those seats! And looks like I have correctly predicted JAL will eventually roll out PY service on this route a while back ;)


With the introduction of 787-8 on Moscow and Delhi routes, JAL will free up the 777-200ER 6 days a week (NRT-DEL will still be operated with 772 once a week). So will JAL expand PY service to more routes? But are there any route left that people are willing to pay for the PY service and can sustain a 772 capacity? Any guess? :)
