Today booked flights for five. Khon Kaen to Suvarnabhumi. I found a considerable variation in prices;

 

Agoda 8,806
Trip.com 7,700
VietJet 10,358 

 

Normally book direct with airlines and haven't noticed such a difference previously?

Did you add any ancillaries like hold luggage or seat selection?  I've noticed with some agents they bump up the price on these so after luring you in with the low headline price they sucker punch you later.

Good advice thanks! No, no extras at all. Booked with Trip.com for 7,700.

Airlines often give a discount to agents who book with them.  If the agent wants to pass on the discount to you, good luck.  If you are booking with a real person in the travel agent, they might consider matching the airline price to keep your custom.

Discount used to be 9%
