Because of my flying pattern and the point of sale costs I maintain a relationship with a TA in CMB. Quite useful and hopefully in both directions, though I tend to end up paying the commission.
BKK-KUL-CMB in Z was significantly cheaper on the website than what the CMB TA could offer. I suppose a BKK TA could have done better but they tend to add credit card surcharges which MH does not.
PS: The route is still a good SC earner for QF
Happy wandering
