Jetstar Asia will add eight additional services to its weekly schedule between Singapore and Bangkok effective, 8 July, a move that will substantially increase competition on one of the busiest routes in the region.

With the new services the airline has six daily flights between Bangkok and Singapore. It is adding over 2,800 seats of new capacity each week on the route, which is likely to lead to even further fares cuts, during Thailand’s rainy season usually an off-peak period for travel.

Jetstar Asia chief executive officer, Barathan Pasupathi, said that Bangkok continues to be one of the biggest markets for Jetstar in its Southeast Asian network.

“We are adding capacity to Bangkok to meet ongoing strong demand from both the leisure market and an increasing number of business travellers attracted to our low fares and our expanding schedule,” Mr Pasupathi said.

“Last year alone, we welcomed 30% more people on this route than in 2011 with more than 2 million passengers carried.”

With the new services, the Jetstar Group will operate 106 flights a week to Thailand with services from Singapore and Sydney to Phuket and services from Singapore and Melbourne to Bangkok.

One-way economy starter fares from Singapore to Bangkok start from S$114 or Bt2,699.

These fares are being challenged by most other airlines on the route including full-service airlines. Customers shop around and recognise that when baggage charges, taxes, insurance, administration fees and seat allocation fees are included there is not much difference between low-cost airline fares and those sold by legacy carriers.

Singapore’s casinos and low-cost airlines are driving travel demand between the two points resulting in a mini-boom in tour groups (casino junkets) and first-time family leisure travel.

Jetstar Asia first took to the skies in December 2004. In 2005, Singapore carrier Valuair became the sister airline of Jetstar Asia, focusing on destinations within Indonesia. Jetstar Asia and Valuair currently operate more than 500 weekly return flights to 23 destinations across 13 countries and territories in the Asia Pacific region.
