Wow that's cheap for full service flight @ 350+ sgd.
I'm thinking to go back before Chirstmas for 4 nights to SG, and did a quick search on Silkair @24K++ BHT, which is insane price. As for Airasia, @ 7k+ BHT.

Currently the Thai airways is offering pre natas promo, Sg - CNX is @ 400++sgd which is good, as normally their charges to CNX is about
550++sgd.

As for transit wise, been there done that, need a really proper planning in timing, otherwise buy non promo domestic flight to go to CNX from Sub ariport in case there's delay, always can call and change the timing for domestic flight.

Bangkok Airways is best for domestic flight from Bkk to CNX in one airport unlike Nok airways and some others domestic you need to go to Don Muang domestic airport, which is wasting time and money.

My two satang worth.
