Bangkok Fares

Ok Almond, I did what you have asked and checked the rates accordingly:

I have set the date to be 4 - 7 Dec (Thurs - Sun). The other weekends would cost about the same with the X'mas one being slightly more expensive (only checked Tiger for that one):

Tiger:

To: 710hrs
Fro: 2010hrs

$319.98

Note: X'mas weekend would be $378.98

Airaisa:

To: 1055hrs
Fro: 1835hrs

$310.00

JetStar:

To: 715hrs
Fro: 2115hrs

$338.00

For comparison sake,

SQ:

To: 845hrs
Fro: 1905hrs

$621.00

Royal Thai:

To: 810hrs
Fro: 1100hrs

$462

Cathay Pacific:

To: 1355hrs
Fro: 1245hrs

$621

I would choose budget anytime. If Thai airlines got better timing, I won't paying extra but well...

Anyway, Almond, the rest is in your hands!
