BA and Malysian try to sell some as everbody knows. But who else I don´t know. Korean? Certainly not, they even get a few new ones soon. Asiana? Probably, but they are opening new routes so its not very likely. North American? I can´t see any. Northwest absolutely not, they just ordered new ones are one of the most likely to order even more. UA? Though I´m pretty sure they have none on order anymore, the usually very exact Bill Harms website keeps on mentioning 7 on order!
My guess is SIA. They are getting new ones on a regular basis and they have a lot of the "oldest" 744s worldwide, built in 1989. 12 year old airplanes are very old in SIA-time so I vote for them.
