don't uses the 747 on the domestic routes.
Sometimes the use the 747 on the BKK
route but only in the high season.
For so far i know they have the 7442 and the 7443 configuration.
The 7442 is the old one with comfortable seats but less space and the 7443 has the new business pods which are not my favourite. They are very narrow and make a lot of noise when you use the motorised seat options.
