Investing in Qantas (ASX:QAN) in 2026, The Fuel Shock Investors Can’t Ignore

Investing in Qantas (ASX: QAN) means dealing with the Middle East crisis, more so than any other share market industry. Up until now, the company had said little to investors, until it released a significant market update this morning (April 14 2026), revising its outlook for the second half of FY26 in response to the situation.

The update confirms what investors have feared since hostilities intensified in late February: fuel costs have moved materially beyond original guidance, creating a genuine headwind to second‑half earnings. Yet the announcement also carries a counter‑narrative. Qantas’ network is expanding, premium international demand has strengthened, and the Group retains meaningful strategic and financial flexibility. The picture is more nuanced than a simple read of the fuel revision suggests.

Qantas’ Fuel Bill: From A$2.5bn to A$3.1–3.3bn

When Qantas reported its 1H26 results at the end of February (about 6 weeks ago), management guided 2H26 fuel costs of approximately A$2.5bn, inclusive of hedging, carbon costs, and transformation benefits. That guidance has been overtaken by the refining margin spike that followed the outbreak of conflict. Jet refining margins — the spread between crude oil and refined jet fuel — surged from US$20/bbl in February to a peak near US$120/bbl. Qantas has hedged roughly 90% of its 2H26 crude exposure, which has provided meaningful insulation on the commodity side. The Group, however, remains largely exposed to refining margins, and it is this component that has driven the revision.

The result is a revised 2H26 fuel estimate of A$3.1–3.3bn, based on forecast consumption of approximately 16.1m barrels and an assumed market jet fuel price of A$185–200/bbl (excluding hedging, into‑plane costs, SAF premiums, and carbon credits). The implied increase from the original A$2.5bn guidance is A$600–800m — a material deterioration by any measure and one that will weigh heavily on 2H26 underlying profit. Qantas notes it is monitoring fuel supply closely, with government and supplier engagement providing confidence in continued availability through April and into May.

Revenue: A Striking Offset

The revenue side of the update is considerably more constructive than the fuel revision implies. The conflict has triggered a meaningful reorientation of travel demand, and Qantas, which does not operate directly to the Middle East, has moved quickly to capture the opportunity.

Group International unit revenue (RASK) growth for 2H26 is now expected at 4–6%, double prior guidance. This reflects a genuine demand shift rather than an accounting artefact. With Middle East airspace closures and multiple carriers suspending services, travellers seeking to reach Europe have turned in material numbers to alternative routings via Australia and Asia. Qantas has responded by redeploying capacity from the US network and the domestic market to increase services to Paris and Rome from Perth.

Group Domestic RASK growth for 2H26 is expected to be approximately 5%, rising to 6% in 4Q26. Both appear sustainable given the 5% domestic capacity reduction applied to 4Q26; demand is holding against a tighter supply of seats, naturally supporting yields.

Qantas vs Jetstar: A Two‑Speed Recovery

The most important operational insight in the update is the widening divergence between the Qantas and Jetstar brands. Qantas International is flying into material capacity growth — 9% in 4Q26 versus the prior corresponding period — supported by strong premium demand and the Europe rerouting tailwind. Jetstar International, by contrast, is contracting meaningfully, with capacity down 7% in 4Q26.

This reflects a fundamental difference in customer bases. Qantas’ full‑service international travellers are relatively price‑inelastic and willing to absorb fare increases; the Group has explicitly cited fare increases as part of its mitigation strategy. Jetstar’s leisure customers, who are budget‑sensitive by definition and may have had Middle East or South‑East Asian travel disrupted, are more exposed to cost‑of‑living pressure and geopolitical uncertainty softening discretionary travel. The revised capacity positions capture this divergence clearly.

Capital Allocation: Discipline in Uncertainty

Qantas has responded to the uncertainty with appropriate capital discipline. FY26 capex has been tightened to A$4.1bn or below — the bottom of the previously guided A$4.1–4.3bn range. The planned A$150m on‑market buyback, announced at the 1H26 result, has not commenced and has been paused pending clarity on the evolving environment. Net debt is now expected to be at or above the midpoint of the A$5.6–7.0bn target range at 30 June 2026, reflecting both the fuel cost deterioration and management’s decision to preserve cash optionality. The A$300m interim dividend (19.8c per share, fully franked) proceeds unchanged and will be paid tomorrow (April 15 2026).

The Group also notes it is well progressed with its FY27 funding plans and characterises its financial position as strong under its Financial Framework. FY27 guidance will be provided at a later date given ongoing volatility: a stance that signals management is unwilling to make commitments in a rapidly shifting cost environment.

Our Assessment On What This Means For Investors Considering Investing in Qantas

The fuel cost revision is unambiguously negative, but its severity should be assessed in context. At the 1H26 result, Qantas reported underlying PBT of A$1.456bn and held A$12.6bn in total liquidity, with net debt at the bottom of its target range. The Group enters this challenge from a position of genuine financial strength rather than fragility. The revenue offset — with international RASK guidance doubled and domestic holding steady; suggests the demand environment is supportive enough to absorb a meaningful portion of the fuel increase through yield management.

The divergence between Qantas and Jetstar also matters. Jetstar’s capacity retreat reduces fuel consumption relative to plan, partially cushioning the per‑barrel cost increase. Qantas International’s 9% capacity growth in 4Q26, by contrast, is occurring at a time when premium fares are rising and demand is robust: precisely the conditions under which margin expansion, not compression, tends to occur.

The share price, which traded near A$12.62 at its 52‑week high before the Iran conflict began, has since fallen to approximately A$8.50, representing a decline of more than 30%. Analyst consensus sits at A$12.19, implying substantial recovery potential if fuel markets normalise. The critical variable is the duration of the refining margin spike. If margins remain elevated through FY27, the earnings impact will extend well beyond 2H26.

If, as many investors expect, margins normalise as Gulf energy infrastructure is restored and shipping patterns adjust, today’s shock is likely to prove transitory rather than structural. In that scenario, Qantas’ revenue momentum, fleet renewal programme, and Loyalty earnings growth could re‑emerge as the dominant drivers, and the current share price discount may ultimately prove to have been an opportunity.
