Australia's national carrier Qantas has announced a series of domestic flight cuts and fare increases after surging jet fuel prices and shifting travel patterns — both driven by the ongoing conflict in the Middle East — significantly altered the airline's cost and demand outlook. In a market update released on Tuesday, Qantas said its fuel bill for the second half of its 2026 financial year is now expected to reach between A$3.1 billion and A$3.3 billion (roughly US$2.2–2.3 billion), up sharply from a prior forecast of around A$2.2–2.5 billion — an increase of as much as A$800 million. Jet fuel prices have more than doubled and remain "extremely volatile", the airline said.

To manage the higher costs, Qantas and its low-cost subsidiary Jetstar will cut domestic capacity by approximately 5% in May and June, reducing the frequency of flights between major state capital cities and trimming some regional services. Four routes will be temporarily suspended — Melbourne to Hamilton Island and Melbourne to Coffs Harbour under the Qantas brand, and Sydney to Busselton and Darwin to Gold Coast under Jetstar — with most suspensions beginning in mid-May. The Adelaide to Mount Gambier route will be cancelled indefinitely, citing persistently low demand and high operating costs. Qantas shares fell more than 3% in early trading on Tuesday before partially recovering.

The capacity freed up domestically and on some US routes is being redirected toward Europe, where demand has surged. Gulf carriers such as Emirates, Etihad, and Qatar Airways — which operate major transit hubs in the Persian Gulf region — have been reducing services due to the regional conflict, prompting travellers to seek alternative routing through Asia. Qantas said it is benefiting from this shift, with flights to Paris and Rome proving particularly popular. International unit revenue is now forecast to grow 4–6% year-on-year in the second half of 2026, double its previous projection, while domestic revenue is expected to rise around 5%, up from an earlier estimate of 3%.

Qantas said it is working with the Australian government and fuel suppliers, who have expressed confidence in supply security through at least May, though the airline flagged it is "closely monitoring" global fuel supply chains given ongoing uncertainty. The airline also uses financial hedging contracts — agreements that lock in a set price for future fuel purchases — to partially shield itself from price spikes, but acknowledged these provide only partial protection at current price levels.

The adjustments highlight how a regional conflict thousands of kilometres away can rapidly reshape the economics of air travel worldwide. For Australian passengers, the immediate consequences are fewer flight options on domestic routes and higher ticket prices. Qantas warned it may need to take "further action" — widely understood to mean additional fare increases — if fuel costs remain elevated.
