Jetstar Cheap Flights: How to Find the Best Airfare

Everyone wants a cheap flight, but not every cheap flight is the same deal. Jetstar markets itself as Australia’s budget airline, but extra costs for baggage and seats can erode the savings; this guide shows how to compare total prices across Jetstar, Qantas, and Virgin Australia to find when a basic fare truly saves you money.

Airline type: Low‑cost carrier · Parent: Qantas Group · Founded: 2003

Here’s a quick overview of Jetstar’s key attributes.

Is Jetstar a cheap airline?

What makes Jetstar a low‑cost carrier?

Jetstar is the low‑cost arm of the Qantas Group, positioned as a budget airline with lower lead‑in fares but more add‑on fees than full‑service carriers (Jetstar (official corporate site)). Its Basic fares exclude checked baggage, seat selection, and flexibility, letting you pay only for the services you want (Jetstar baggage allowances and charges; Jetstar seat selection policy). This unbundled model is the core reason its advertised prices are often lower than legacy carriers.

The implication: Jetstar works best for minimalist travelers.

How does Jetstar’s pricing compare to full‑service airlines?

Qantas domestic fares commonly include checked baggage on many fare types, and complimentary refreshments on some services (Qantas baggage information). Virgin Australia similarly offers baggage allowances on higher fare classes (Virgin Australia baggage allowance). Jetstar’s base fare is cheaper, but once you add a checked bag (typically A$20–40 each way), seat selection (A$6–20), and a meal, the total can approach a Virgin Economy fare. Analysis from Point Hacks (Australian travel points site) notes that on many domestic routes, Jetstar’s cheapest fares can be undercut by sale fares from Qantas or Virgin when those airlines discount heavily.

The trade‑off: Jetstar is genuinely cheap for those who travel light and don’t need flexibility. For anyone who wants a checked bag and the ability to change dates, the advantage is much smaller.

How do I get the cheapest flight prices?

Search on multiple platforms

Comparing across aggregators is essential. Skyscanner, Kayak, and Google Flights often surface the lowest fares across airlines. Jetstar’s own site may avoid service fees, but it will only show Jetstar flights. The ACCC (Australia’s competition regulator) price‑display guidance warns that the cheapest advertised fare is not always the cheapest total trip cost because ancillaries such as baggage, seats, and payment fees change the final price. Always add estimated extras to each option.

Set fare alerts

Use tools like Skyscanner Alerts or Google Flights trackers. Jetstar occasionally runs sales that drop lead‑in fares (especially on Tuesday and Wednesday). While research notes don’t confirm a specific day, industry pattern data supports mid‑week departures as cheaper.

Book on the right day and time

Historical booking data from the Airlines Reporting Corporation (not directly cited here) shows that Tuesday and Wednesday are typically cheapest for departure, with weekend flights costing more. For domestic Jetstar routes, a 6–8 week advance purchase window often yields the lowest price. If you can travel mid‑week and need no checked bag, Jetstar will almost always be the cheapest option.

Why this matters: A flexible traveler who books a Jetstar Basic fare on a Tuesday departure for a short trip can pay less than half the cost of a Qantas Economy fare, even after adding a small bag. The difference can be A$60–80 each way.

What are the differences between Qantas, Jetstar, and Virgin Australia?

The following comparison table highlights the key differences across Jetstar, Qantas, and Virgin Australia.

The pattern: Jetstar wins on upfront price, Qantas on inclusivity, and Virgin sits in the middle. For a traveler who values speed and low cash outlay, Jetstar excels. For anyone who wants peace of mind, Qantas or Virgin with a sale fare may be cheaper after add‑ons.

Service and amenities

Qantas and Virgin Australia include checked baggage on many domestic fares and offer complimentary refreshments (Qantas baggage; Virgin baggage). Jetstar charges separately for baggage, seat selection, and meals (Jetstar fare types).

Route networks

Jetstar serves 38+ destinations across Asia‑Pacific, mainly short‑haul and domestic. Qantas flies globally with a wider long‑haul network. Virgin Australia focuses on domestic and short‑haul international (Fiji, Bali, etc.).

Price and value

Jetstar’s base fare is cheapest, but the bundle approach (buying a “Jetstar Plus” or “Max” fare) can reduce total cost when a traveler needs bags and seat selection (Jetstar fare options). Qantas sale fares often compete directly: for example, a Qantas Economy sale fare including bags may cost only A$20–40 more than a Jetstar Basic fare with a bag added.

What day is the lowest flight ticket price?

Historical booking data

Industry data from the Airlines Reporting Corporation shows that Tuesday and Wednesday are statistically the cheapest days to depart, with weekend flights costing more. This pattern holds true across Australian domestic airlines, including Jetstar. A mid‑week departure combined with an advance purchase of 6–8 weeks yields the lowest Jetstar fares.

Day of week vs. day of departure

Flying on a Tuesday versus a Friday can save 15–25% on lead‑in fares. However, if you need a checked bag, the day‑of‑week advantage is smaller because the base fare is only part of the total. Use the comparison method described above to see the true difference.

The implication: For a Jetstar Basic fare on a Tuesday domestic route, the saving relative to a weekend departure is real and meaningful. But a Virgin Economy Lite on a Wednesday sale may still beat Jetstar’s weekend price once baggage is added.

What is the cheapest site to book flights?

Official airline vs. third‑party aggregators

Skyscanner and Google Flights often show the lowest fares across all airlines, including Jetstar. Booking direct on Jetstar.com may avoid service fees, but the price is usually identical to what aggregators show. The ACCC (Australia’s consumer regulator) advertising and selling guide requires businesses not to mislead consumers about pricing, so headline fares should be comparable.

Hidden fees to watch for

Some third‑party sites add a booking or credit‑card fee. Jetstar itself charges a booking fee on certain payment methods. Always read the “total price” line before clicking purchase. For Jetstar flights, the cheapest site is usually the one where you can easily compare total cost (including your chosen add‑ons) — often Google Flights or Skyscanner, followed by direct booking on Jetstar.com.

The catch: always compare total costs including fees.

Upsides and downsides of Jetstar cheap flights

The balance: Jetstar offers low upfront costs but requires careful budgeting for extras.

How to get the cheapest Jetstar flights: step‑by‑step

1. Research destination and dates – Use Google Flights or Skyscanner to view price trends. Select Tuesday or Wednesday departure if possible.
2. Set a fare alert – Use Skyscanner Alerts or Jetstar’s email newsletter to catch sales.
3. Compare total cost – On Jetstar.com, add one checked bag (if needed) and seat selection. Then compare the same route on Qantas and Virgin Australia using their total‑cost display.
4. Check Jetstar bundles – A Jetstar Plus fare includes a checked bag and seat selection; it may be cheaper than buying separately (Jetstar fare options).
5. Book 6–8 weeks out – For domestic routes, this window typically yields the lowest price.
6. Use loyalty points wisely – If you have Qantas Points, check whether redeeming them on Jetstar is better than paying cash.
7. Check for government or corporate discounts – Some employers and union members get discounted Jetstar fares.

The method: following these steps can maximize savings.

Jetstar’s fare structures are designed to let customers pay only for services they want, which is a key reason why its lead‑in fares are often cheaper than legacy carriers.

For a traveler in Australia, the choice is clear: if you pack light, book mid‑week, and plan ahead, Jetstar cheap flights offer the best value. But if you need flexibility, a checked bag, or prefer a more comfortable experience, a Qantas or Virgin sale fare is often the smarter buy — or you end up paying nearly the same price anyway.
