FREQUENT FLYER GLOSSARY
What is a connection vs a stopover?
Connection vs stopover is the line fare rules draw between changing flights inside the time a carrier allows for a connection and breaking the journey for longer. In American Airlines' Conditions of Carriage a stopover is a planned stop in a city or airport for over 4 hours, so the test turns on how long the break lasts rather than on what the traveller does while waiting. [2]

Key takeaways
- A connection is a change of flight inside the carrier's connecting window; a stopover is a planned break that runs beyond it. [2]
- American Airlines puts the stopover line at a planned stop in a city or airport of over 4 hours, in Conditions of Carriage updated 13 August 2026. [2]
- The boundary feeds into fare validity, refunds after a schedule change, and even whether bag fees are charged a second time. [2]
- Workable connecting times are published station by station: IATA's Station Standard Minimum Connecting Time(s) manual covers more than 400 of the most connected airports worldwide, representing 90% of international connections. [1]
How are a connection and a stopover defined?
A connection is a change of flight in the middle of one journey, made within the time the carrier allows for that change: the traveller stays in transit and the journey carries on. A stopover is a break long enough to count as a stop in its own right, with the traveller leaving the airport and spending time in the city before continuing. Fare rules and conditions of carriage fix where one ends and the other begins, because the label decides which requirements the ticket has to satisfy.
American Airlines writes that line into its own contract: a stopover is "a planned stop in a city/airport for over 4 hours". [2] The term is then used consistently across its conditions, including the schedule-change and refund provisions described below. [2]
At industry level, the time needed to change flights is published airport by airport rather than left to the traveller to judge. IATA's Station Standard Minimum Connecting Time(s) manual, described as the "Airport Standard MCT", covers more than 400 of the most connected airports worldwide, representing 90% of international connections. [1] The same publisher's Passenger Tariffs Conference Composite Manual, formerly the Passenger Standards Conference Tariffs Manual, contains definitions alongside mileage, fare and currency principles and interline baggage rules. [1]
Why does the connection-versus-stopover boundary matter?
Because the fare a ticket is priced on carries requirements about the journey, not only about the flights. American's conditions state that a ticket is valid only where the traveller meets all the fare requirements, and they list dates of stay — a Saturday night or a weekend, for instance — next to military status, official government business and attendance at an event as requirements a fare may impose. [2] Where those requirements are not met, the ticket is not valid. [2]
Stopovers and connections also shape what happens when plans change after booking. American lists the number of stopovers or stopover cities among the details that may change between purchase and departure, and says it will try to contact the customer in advance to rebook a flight or move them to a similar seat or cabin. [2] In the other direction, an increased number of connections is one of the eligible itinerary changes that lets a customer choose not to fly and receive an automatic refund of the ticketed fare, including taxes and fees. [2]
Baggage rules read the length of a stop differently from most travellers. On American, bag fees may have to be paid again where the connection on American is more than 16.5 hours later. [2]
How does a fare-rule stopover differ from an award stopover?
The stopover described on this page is a fare-rule idea: it decides whether a purchased ticket still matches the fare it was sold on, and it is answered by the fare rule and the carrier's conditions of carriage. [2] An award stopover belongs to a different set of documents — the redemption rules of the frequent flyer programme whose miles are being spent. Those rules are set out on the airline stopover programme page and in stopovers and open jaws, and they are not restated here. Because the two come from different documents, a traveller checking one should not assume it settles the other. [2]
Exceptions and limits
- The four-hour figure belongs to American. It is written into American Airlines' Conditions of Carriage and applies to travel under that contract; it is not a threshold that can be carried across to another carrier's fare. [2]
- Fare requirements come from the fare, not the airport. Dates of stay such as a Saturday night or weekend, event attendance and status-based fares are all fare requirements on American, and failing them makes the ticket invalid. [2]
- Not flying the whole journey is a booking practice, not a stopover. American prohibits buying a ticket without intending to fly all flights (hidden city ticketing) and combining two or more roundtrip excursion fares end-to-end to get around minimum stay requirements (back-to-back ticketing), and reserves the right to cancel any unused part of the ticket. [2]
- A missed connection is handled as a disruption. Where a delay could cause a missed connection, American says it will rebook the customer on the next American flight with available seats at no additional cost, and on a partner airline if no American flight is available until the next day and the disruption was its own. [2]
- Connecting times are station-specific. IATA's station minimum connecting time data covers more than 400 of the most connected airports worldwide, representing 90% of international connections. [1]
Frequently asked questions
What counts as a stopover under American Airlines' conditions of carriage?
A planned stop in a city or airport for over 4 hours, according to the definition in American's Conditions of Carriage. [2]
How long can a connection be before it becomes a stopover?
The threshold sits in the fare rule and the carrier's conditions: American uses a planned stop of over 4 hours [2], while the workable time for changing flights at a given airport is published through IATA's station minimum connecting time data [1].
Can a long connection affect baggage fees on American?
It can, because bag fees may apply again where the connection on American is more than 16.5 hours later. [2]
Why does an extra connection matter for refunds?
American lists an increased number of connections among the itinerary changes that make a customer eligible for an automatic refund of the ticketed fare, including taxes and fees, if they choose not to travel on the changed itinerary. [2]
Is a fare-rule stopover the same as an award stopover?
No. The fare-rule version comes from the fare and the carrier's conditions of carriage [2]; award stopovers follow the redemption rules of the frequent flyer programme being used, covered under airline stopover programme.
