It's a 333.

There should be no F on this route any more, unless MH hasn't finished updating all of its 333's, which used to have a 60" pitch F cabin and a 40" pitch C cabin. Now there is only a larger C cabin with 45" pitch.

Nothing very special I noticed in F on this route last year: electrically reclinable cloth seats with legrests, similar to a good long-haul C seat, good food, wine, and service, and mostly, less people than in the usually sold-out C cabin.

Also this gave access to the superior F side of MH's lounge at KUL. In BKK MH uses TG lounges.
