Airline timetables are not guarantees and do not form part of the contract

Most airline conditions of carriage say that published departure and arrival times are estimates, not guarantees, and do not form part of the contract of carriage. That single clause decides whether a disrupted passenger has any contractual claim arising from the time itself.

The wording varies more in drafting architecture than in plain meaning. Cathay Pacific states it directly; American Airlines folds it in by reference; EVA Air and Singapore Airlines tie it to a no-responsibility-for-connections clause. Where EU261 or US DOT rules apply, the disclaimer cannot waive covered rights.

The clause that quietly writes the timetable out of the contract

Cathay Pacific gives the clearest version of the schedule disclaimer in this comparison. Its conditions of carriage state that times printed in timetables or elsewhere do not form part of the contract of carriage, and that those times are not guaranteed. When necessary, the airline may also alter or omit stopping places shown on the ticket, or substitute another carrier or aircraft — more room to change the operation than the schedule clause alone suggests.

Singapore Airlines handles the same ground in a single provision. That clause puts a ticket or timetable time outside the contract, declines any duty to get a passenger onto a connecting flight, and reserves the right to move a schedule, drop a ticketed stopping place, or substitute a different carrier or aircraft when circumstances demand. Each of those denials stays subordinate to applicable law.

According to EVA Air‘s conditions of carriage, Article 10.1.1 places the non-guarantee and the connection disclaimer in the same clause. Article 10.1.2 then adds a refund route when a significant schedule change is unacceptable and no acceptable alternative can be arranged. That remedy is the exception a traveler actually needs to know about.

Malaysia Airlines, a sixth carrier beyond the original five, states the same non-guarantee in section 10.1. It does not guarantee departure or arrival at timetable or published-schedule times, and it says those schedules form no part of the contract. Elsewhere in the same document, the carrier promises best efforts and says it will try to notify passengers of schedule changes.

How American Airlines and AirAsia reach the same result by a different route

American Airlines does not publish a single sentence saying the timetable is not part of the contract. Its passenger agreement instead pulls the conditions of carriage, fare rules, and tariffs in by reference, so the disclaimer reaches the traveler through that incorporation mechanism — assembled from several documents rather than stated in one place.

AirAsia‘s platform terms work the same way by reference to the operating airline’s carriage terms. Earlier AirAsia material treated the itinerary itself as prima facie evidence of the contract, which places the schedule document inside the contract rather than outside it. The current official page confirmed that incorporation, but it did not verify a clause-level schedule disclaimer.

That difference changes where a passenger looks. On Singapore Airlines or EVA Air, the disclaimer is one identifiable clause. On American or AirAsia, it is distributed across documents a traveler would need to assemble to see the whole posture.

Whether those architectures produce different legal outcomes was not established by the research.

Where a regulator writes a rule the disclaimer can’t erase

Under Article 15 of EU Regulation 261/2004, a carrier cannot use a contract term to cut down or waive the obligations the regulation places on it. The European Commission‘s interpretative guidance reads the regulation alongside the relevant Court of Justice case law. So a timetable disclaimer cannot defeat a qualifying EU261 right — but whether that right exists at all still depends on the flight and the disruption meeting the regulation’s tests.

US law works differently in kind. The research turned up no comparable rule that voids every schedule disclaimer across the board; American protections instead arrive as discrete duties, among them tarmac-delay limits and flight-status requirements. Canada’s Air Passenger Protection Regulations, published in the Canada Gazette, add a 30-minute status-update duty once the original departure time has passed. That duty operates independently of any timetable disclaimer, not in place of it.

No Tier 1 or Tier 2 ruling turned up in this research that decided a passenger’s schedule-change claim by applying one of these carriers’ timetable disclaimers on its own. The closest authority is the European Commission’s 2024 guidance, which helps on the regulatory-rights question but is not a judgment naming a schedule disclaimer — a limit on what this comparison can prove.

What this means for you

A traveler who assumes the carrier is contractually bound to the published time may choose a tighter, cheaper itinerary than is prudent. Because the risk of a missed connection sits with the passenger under most of these contracts, a missed connection alone does not create a rebooking obligation. The no-connections disclaimer sits inside the same clause as the non-guarantee, not in a separate provision.

EU261 compensation runs in three distance bands — €250, €400 and €600 — but only when the flight and disruption meet the regulation’s conditions. Under the Montreal Convention, carrier liability stays inside the convention’s scope, and a timetable is not something the convention guarantees.

The operational takeaway is to check which jurisdiction covers the route before the disruption, not after. An EU-covered flight gets one set of duties; a US-covered flight gets another, narrower set. A schedule disclaimer can still leave a passenger with no contractual claim when no regulation steps in.

Key terms

Conditions of carriage

A conditions-of-carriage document is an airline’s own set of contractual terms covering ticketing, baggage, scheduling, and liability. Carriers publish it separately from the ticket, and some — American Airlines and AirAsia among them — pull it into the passenger agreement by reference rather than restating it. Because the carrier drafts the document unilaterally, its schedule clause is exactly the kind of term Article 15 of EU Regulation 261/2004 blocks from waiving EU261 rights.

EU Regulation 261/2004

EU Regulation 261/2004 is the European Union’s passenger-rights law, imposing compensation and assistance duties on carriers for delayed, cancelled, and overbooked flights. Its Article 7 sets compensation in three distance bands, and Article 15 blocks any contract term that would limit or waive the rights the regulation grants. Because the regulation applies by route and disruption rather than by carrier, the same airline can owe compensation on one itinerary and nothing on another.

Montreal Convention

The Montreal Convention is a multilateral treaty that governs airline liability for international carriage of passengers, baggage, and cargo. It sets the framework for compensation claims, and its mandatory rules cannot be displaced by contract. It does not guarantee a timetable, so a schedule change that causes no injury or baggage loss generally falls outside what the convention pays for.

Air Passenger Protection Regulations

Canada’s Air Passenger Protection Regulations are the country’s passenger-rights rules for itineraries that touch Canada. They require carriers to supply disruption information and, once the original scheduled departure has passed, status updates every 30 minutes until a new takeoff time is confirmed or alternative arrangements are booked. In defined situations they also require minimum treatment or compensation — duties that operate independently of any timetable disclaimer.
