also bear in mind that TG has been using the a B772 for BKK-HKG (TG628 depart 10:30) for the past 2 months, this has to be the best for this leg. It has the latest lie-flat seats installed...new entertainment etc.....BUT as you know TG is infamous for equipment change, which is what happened to me last month (B772 to B777) and as I was planning my travel for the remaining of this yr, I see they no longer fly this route in Dec.

You might want to keep an eye open to their schedule, if the B772 is available next April surely it would be the top choice.
