Long flight

[Piamed]

Some airlines like KLM, to Manila and Virgin and Air New Zealand (to HK) have a class called premium economy or something similar with more leg room and width. Not nearly as expensive as Business class.

might be worth a try

KLm unfortunately does not have a Premium Economy yet but their 'partner' Air France does, so do BA, BMI, SAS, Thai Airways and Singapore Arlines, to list the main ones.

There are some good deals to be had on Business Class with KLM if one has enough Flying Blue Miles.
