If a lower fare (per passenger) is found within 2 hours of making your online flight booking from the airline's official web page, we will provide a refund of the fare difference, as long as it is at least SGD30. To be eligible for the Best Fare Guarantee, the lower fare must be available for purchase from qualified web pages such as lowfarefinder.
