Singapore Airlines flights - Cheap Air Travel - Budget Airlines

Jetstar Asia
One of Southeast Asia's low cost giants, JetStar Asia operates numerous low cost routes from its hub at Singapore's Changi airport to destinations all over Southeast Asia.Note that JetStar Asia is the only Asian budget carrier at present flying from Singapore direct to Hong Kong - though see Tiger Airways for flights to Macau.

It's also the only Singaporean low cost airline flying to Phnom Penh and Siem Reap in Cambodia, Yangon in Myanmar and Taipei in Taiwan.

Tiger Airways
The main competitor airline to Jetstar Asia, Singapore's Tiger Airways flies to one or two of the same destinations including Bangkok and Phuket in Thailand. But note that in its bid to become a Ryanair-style lowest cost airline, Tiger Airways often prefers to fly to secondary airports - to Macau, for instance just across the water from Hong Kong, and to Clark Field, serving Manila, rather than to the Philippine capital's main airport.

From Singapore, Tiger Airways has the widest selection of low cost routes to Thailand and is also the only Singaporean budget carrier flying direct to China. Tiger Airways is also, along with Jetstar Asia, one of the few Southeast Asian low cost airlines flying to Australia.

AirAsia

The Thai branch of Air Asia operates a single budget route from Bangkok to Singapore for a cheaper fare - on average - than either Jetstar Asia or Tiger Airways. If few cheap flights appear to be available for the time period you wish to travel, check out both competitor airlines.

Air India Express
Air India Express curently operates three low cost routes between Singapore and India. It is the only budget carrier offering cheap flights between Singapore and Kolkata and Tiruchirapalli, but see Tiger Airways for more competitive fares to Chennai - as well as flights to Kochi.

Bangkok Airways
Not a budget airline, Bangkok Airways nevertheless offers relatively cheap one-way flights direct from the island of Koh Samui to Singapore. This may prove more convenient than traveling overland through southern Thailand and Malaysia or else traveling north to Bangkok where three dedicated low cost carriers connect the Thai capital to Singapore.

Cebu Pacific Air
Based in the Philippines, Cebu Pacific Airlines operates low cost flights from Singapore to the far east of Southeast Asia, in competition with both Jetstar Asia and Tiger Airways.
 

Lion Air
Indonesian low fare airline Lion Air flies from Singapore to Jakarta in competition with both Adam Air, also based in Indonesia and Valuair, based in Singapore. Either of the latter are likely to have cheaper fares than Lion Air.

Mihin Lanka
Sri Lanka's only budget airline to date now operates direct low fare flights connecting Singapore to the Sri Lankan capital city of Colombo.
