About Jetstar
Jetstar is the low-cost airline of the Qantas Group. It is headquartered in Melbourne and flies under the code JQ. Within Australia it links the big cities with holiday destinations such as the Gold Coast, Cairns and Tasmania, and it also runs domestic flights inside New Zealand. International routes head to places popular with Australian leisure travellers, including Bali, Thailand, Vietnam, Japan, Fiji and Hawaii. Short-haul aircraft have a single Economy cabin, while long-haul aircraft add a Business cabin. Jetstar is not a oneworld member, even though its parent is.
Jetstar fares appear in your search results whenever our flight suppliers offer them for your route and dates. Use the IATA.co booking portal to search, or the flights API if you are integrating flights into your own product, and pay from your prepaid balance. Jetstar sells a basic fare plus bundles, so bags and meals may or may not be included. The inclusions and fare rules are shown before you confirm.

Jetstar is a low-cost carrier, based in Australia, operating mainly from Melbourne (MEL). It is not part of a global airline alliance.
Booking Jetstar fares as a travel agent
Travel agents book Jetstar fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live JQ fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Jetstar results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search Jetstar (JQ) through the flights API
Developers and agencies can run the same Jetstar search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code JQ and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
