The aircraft generally (always?) has F seats but has been sold as 2-class in the recent past with the F section closed or offered to elites/full-fare J pax with business service. This is a recent change as when I booked a July ticket back in February F was unavailable but I was able to change the ticket today.
That flight is HKG-BKK-DEL. HKG/BKK is one of the routes most subject to a/c substitution, so don't count on anything other than the possibility of last minute a/c substitutions. Just checked a few random dates in June and found 2 class 333s operating this flight.
