Need a bit of help doing my first DC redemption! Looking at booking business class on TG from ISB to KUL, via BKK, in July next year. Am I likely to be able to find three seats? We can be flexible on dates to a certain extent.

Also, is it possible to book a stopover in BKK on the return leg? We're hoping to spend a couple of weeks there with family.

Cheers for any advice, from a complete newbie at this sort of thing...
