Flight delayed or cancelled: what airlines owe you in Australia

Your flight is delayed by four hours. Or cancelled outright. The airline's app says "operational reasons" and the gate agent hands you a $10 meal voucher. You want to know whether you're entitled to more — a full refund, a replacement flight, or compensation for the costs you've now incurred. The answer is more nuanced than a single yes or no, but Australian law gives you more leverage than most airlines will volunteer.

Quick answer

Australia does not have a single dedicated flight-delay compensation statute the way the European Union does with its EC 261/2004 regime. Your rights come from two overlapping sources: your contract with the airline (the ticket conditions and fare rules you agreed to at booking) and the Australian Consumer Law (ACL), where you acquired the flight as a consumer within the meaning of section 3 of the ACL.

Under the ACL, a delay or cancellation caused by the airline — rather than an event genuinely outside its control — can engage three consumer guarantees for services: that they be supplied within a reasonable time (section 62), performed with due care and skill (section 60), and fit for a disclosed purpose or result (section 61). For many delay and cancellation disputes, section 62 is often the most practical starting point, especially where the issue is whether the airline supplied the travel service within a reasonable time after the disruption. If the failure is serious enough to be a major failure, you may cancel the contract and seek a refund for the unconsumed portion, or keep it and seek compensation or a price reduction reflecting the drop in value. For a non-major failure, the airline gets the first reasonable opportunity to put things right — typically by rebooking you on the next available service.

Your ticket conditions may also give you independent contractual rights to refunds or rebooking, sometimes going further than the ACL baseline. Two preconditions matter: you need to raise the issue with the airline directly before escalating, and the guarantees apply only where you acquired the service as a consumer under section 3, whose exclusions differ for goods and services — if you booked through a business for re-supply, check how section 3 applies to you.

What the law actually says

The ACL consumer guarantees for services

When you buy a domestic or international flight ticket from an airline operating in Australia, you are generally acquiring a service. The consumer guarantees apply automatically where you acquired that service as a consumer under section 3 — a gateway an ordinary leisure or business traveller clears comfortably, since it covers services bought for under the section 3 price threshold as well as services of a kind ordinarily acquired for personal, domestic or household use.

Three guarantees are most relevant to flight disruptions:

• Section 62 — Supply within a reasonable time. Where the contract does not fix the time for supply, the service must be supplied within a reasonable time. A ticketed departure time may fix that time contractually, so section 62 often does its real work on what happens after the disruption — how long the airline takes to actually get you where you were going.
• Section 60 — Due care and skill. The airline must perform the service with the care and skill of a competent carrier. Operational issues within the airline's control — maintenance, crew rostering, scheduling — may support this guarantee depending on the evidence available to you.
• Section 61 — Fitness for purpose or result. If you made known to the airline or the booking provider a particular purpose or desired result — reaching a connection, attending a time-sensitive event, arriving by a specific time — and the circumstances do not show that relying on the airline's skill and judgment was unreasonable, section 61 may be relevant. A private reason you never communicated is unlikely to be enough.

When a guarantee is breached, the remedies for services sit mainly in sections 267–270 of the ACL, with section 268 defining what makes a failure major. (Sections 259 to 263 deal with goods, which is a different framework.) The key distinction is between a major failure and a non-major failure.

Major failure vs non-major failure for services

Under section 268 of the ACL, a failure to comply with a services guarantee is major if:

• A reasonable consumer, fully aware of the nature and extent of the failure, would not have acquired the service;
• The service, or any product resulting from it, is substantially unfit for its common purpose and cannot be remedied within a reasonable time;
• The service, or any product resulting from it, is substantially unfit for a particular purpose you made known to the airline and cannot be remedied within a reasonable time;
• The service does not achieve a result the consumer made known to the supplier, and cannot be remedied within a reasonable time; or
• The service creates an unsafe situation.

A flight cancelled with no alternative offered for 24 hours may meet this threshold — but it depends on the cause of the cancellation, the alternatives the airline offered, and whether a time-critical purpose had been made known to it. A short delay of an hour or two, with the flight ultimately departing, is much less likely to.

For a major failure, you may cancel the contract and recover a refund for the unconsumed portion, or keep the contract and seek compensation or a price reduction reflecting the drop in value.

For a non-major failure, the airline gets the first reasonable opportunity to remedy the problem — typically by rebooking you. If it fails to do so within a reasonable time, you may be entitled to have the failure remedied elsewhere and recover the reasonable costs, or to cancel the contract where the statutory conditions are met.

What "due care and skill" does not cover

The ACL does not make airlines an insurer of all travel disruptions. Delays caused by genuinely unforeseeable external events — severe weather, air traffic control restrictions, a security incident — are less likely to constitute a failure of due care and skill, because the airline did not cause the problem through its own conduct. The closer the cause sits to something within the airline's operational control, the stronger your position. The ACCC also treats the length of the delay, its cause, and whether the airline moved you onto an alternative service as relevant to what remedy is reasonable.

Misleading conduct

If the airline made a representation about departure times, connections, or service features that was false or misleading, section 18 of the ACL may also be relevant. Advertising a non-stop flight that in fact requires a connection, or continuing to sell seats on a timetable the airline knows it cannot operate, may raise misleading-conduct issues depending on the facts. See our section 18 guide for more on how this works.

When this applies (and when it doesn't)

The ACL consumer guarantees for travel services are likely to apply to travel within Australia, travel from Australia supplied by an international business, and travel to Australia booked through an Australian website. Beyond that, the guarantees are likely to apply when:

• You acquired the flight as a consumer under section 3 — which an ordinary personal or business traveller normally will.
• The section 3 exclusions do not apply (for example, you are not a travel agent acquiring tickets for re-supply).
• The disruption was caused by something within the airline's operational control, not a genuine external event.

The ACL is less likely to assist when:

• The delay was caused by severe weather, air traffic control, or another event genuinely outside the airline's control.
• You changed your mind about travelling and want a refund for a non-refundable fare — change-of-mind is not a consumer guarantee ground.
• The airline offered a reasonable rectification (a rebooking on the next available flight) and you declined it.
• The ticket was bought from an overseas seller with no meaningful connection to Australia — the ACL can still apply where the seller supplied directly to an Australian consumer, but enforcement may be difficult in practice.

Your ticket conditions may give you additional rights, and most major Australian carriers publish conditions of carriage covering meal vouchers, accommodation and rebooking. Read them — they sometimes exceed the ACL baseline and form part of your contract. But an airline's own compensation policy cannot replace or limit the consumer guarantees, and a term purporting to exclude them does not work.

For international flights, the Montreal Convention may provide a separate basis for claiming proven loss caused by delay in international carriage. It is not an EU-style fixed payment: it compensates damage you can demonstrate, and it carries its own liability limits, defences and strict time limits. If your delay caused significant consequential losses on an international route, check whether it applies to your situation and how long you have to act.

What to do today

If your flight was delayed or cancelled and you believe the airline owes you more than it has offered, here is the sequence that tends to work:

1. Document everything at the airport. Note the scheduled and actual departure times, photograph the departure board, and keep every receipt for meals, accommodation or transport you had to pay for. Ask the gate agent for the reason for the delay in writing if you can.
2. Check your ticket conditions. Find the airline's conditions of carriage and identify what it promises for a delay or cancellation. That is your contractual baseline before you reach the ACL.
3. Submit a formal complaint to the airline in writing. Email or an online form creates a record. State the flight details, the nature of the disruption, why you believe the airline is responsible, and what you are seeking. Reference sections 60, 61 and/or 62 where they apply — for an unreasonable delay, section 62 is usually the one to lead with.
4. Give a clear deadline. Request a response within 14 days and say you will escalate without one.
5. Keep all evidence. Boarding passes, booking confirmations, receipts, correspondence — all of it.

If you're not sure how to frame the written complaint, fairgo can generate a demand letter for free in about 90 seconds. The wizard identifies the relevant ACL sections and produces a letter you send under your own name.

What if the business refuses

If the airline rejects your complaint or doesn't respond within a reasonable time, you have several escalation options:

The Airline Customer Advocate (ACA) is a free service that handles unresolved complaints about participating Australian airlines once you have complained to the airline first. Check the ACA or the current government aviation-complaints site for which airlines participate and what eligibility limits apply before lodging — participation and scope change. The ACA can investigate and make recommendations, but its determinations are not legally binding in the way a court order would be.

Your state or territory Fair Trading body offers a free conciliation service for many consumer disputes, and may be an option alongside or after the ACA depending on the airline, your state and eligibility. Generally you need to have already tried to resolve the dispute with the business directly. Conciliation is voluntary and confidential; a Fair Trading body cannot make binding orders or compel the airline to pay. Full contact details for every state and territory body are at /agencies.

State and territory tribunals and courts are the binding forum if you need an enforceable outcome. Which forum is correct depends on the nature and amount of your claim and the enabling legislation in your state. For many ordinary ACL disputes the Magistrates Court (or equivalent) may be correct rather than a specialist tribunal — jurisdiction depends on the tribunal's enabling legislation and must be confirmed before filing. You can often file without a lawyer. Check the official site of your state tribunal or Magistrates Court for current claim thresholds and filing fees, as these change. See our tribunal comparison guide for an overview.

The threat of escalation, set out clearly in a written demand letter, often moves airlines that have previously stonewalled. Businesses generally prefer to settle before a formal hearing.

Common mistakes

A few patterns come up repeatedly in flight-delay disputes:

• Assuming Australia has EU-style fixed compensation. It doesn't. There is no Australian equivalent of the EU's fixed per-passenger payment. Your entitlement depends on the specific failure, your losses, and whether the ACL or your ticket conditions apply — not a flat statutory amount.
• Accepting a voucher without checking your full entitlement. A $10 meal voucher may be all the airline is contractually required to provide for a short delay, but for a longer disruption caused by its own operational failure your ACL rights may entitle you to more. Don't sign anything that waives further claims without understanding what you are giving up.
• Conflating weather delays with airline-caused delays. Weather is generally outside the airline's control; maintenance failures, crew shortages and scheduling errors generally are not. The cause matters enormously.
• Not keeping receipts. Recovering out-of-pocket expenses requires proof of them. Keep every receipt for meals, taxis, accommodation or alternative transport.
• Going straight to the ACCC. The ACCC investigates systemic conduct and does not resolve individual delayed or cancelled flight complaints. For your specific claim, the ACA, Fair Trading conciliation, or a court or tribunal is the right path.
• Waiting too long to complain. Delay weakens your position, and international claims under the Montreal Convention carry their own strict time limits. Raise the issue in writing as soon as you can and keep a dated record.
