Navigating the world of aviation can often feel like deciphering a complex code. One such code is the concept of Minimum Connect Times (MCT). As the most-trusted source of aviation industry information and analytics, we at Cirium are here to simplify this term for you. Let us delve into the world of MCT and understand why it is a crucial aspect of airline operations and passenger experience.
What Is Minimum Connect Time (MCT)?
Minimum Connect Time (MCT) refers to the shortest allowable time required for a passenger and baggage to make a connecting flight at an airport. It’s a buffer time that airlines set to ensure passengers have enough time to disembark one flight, navigate through the airport, and board their connecting flight.
For example, if an airport has an MCT of 45 minutes, it means that the airline believes a passenger and baggage can comfortably make a connection within this time frame.
Understanding the prevailing MCTs at different airports is of paramount importance to airline network planners.
The Significance of MCT
MCT plays a vital role in ensuring smooth airline operations and enhancing passenger experience. Here’s why:
- Enhancing the Passenger Experience: By allowing ample time for passengers and baggage to make their connections, airlines can improve passenger satisfaction and alleviate the stress associated with tight connections.
- Efficient Operations: Minimum Connection Times (MCT) play a crucial role in optimizing flight schedules, minimizing the likelihood of missed connections with lost or delayed baggage, and preventing departure delays.
- Strategic Network Planning: Understanding the prevailing MCTs at different airports is of paramount importance to airline network planners. These MCTs shape the connectivity of potential connecting flights and are essential when introducing new services. Airlines may even adjust flight schedules by a few minutes to ensure passengers can seamlessly make their connections.
Drivers of MCT Rules
Airlines and airports establish varying connection times based on several factors. MCTs are not fixed and may be subject to adjustments due to airport construction or alterations in airline agreements.
Factors that affect MCTs include:
- Airport size and navigability: Some airports are larger and more challenging to navigate than others.
- Connection type: There are four main connection types:
- Domestic to Domestic (DD),
- Domestic to International (DI),
- International to International (II), and
- International to Domestic (ID).
DI or ID connections usually require more time due to passport control, customs, and potential terminal changes at larger airports.
- Interline or online connections: If you are changing carriers in addition to aircraft, your connection time may vary.
- Aircraft type: Boarding and disembarking passengers from larger aircraft, such as the A380, typically take longer.
- Terminal location: If you arrive at one terminal but need to depart from another that is far away, it can affect your MCT.
- Ground transfers: If you land in one airport but depart from another, like from JFG to LGA, expect a higher MCT.
- Flight number: Some airlines adjust their MCTs on a flight-by-flight basis. An example of this is when a flight operates when a CBP (Customs and Boarder Protection) Pre- clearance facility is closed.
As an example of an MCT use-case, let’s consider a scenario where you’re traveling from Canada to the US via Air Canada. If your last layover before entering the US was in Calgary (YCC), a 50-minute connection would suffice. However, if your layover was in Vancouver, you would need 70-minutes. The minimum connect time at this airport is longer due to its larger size, multiple terminals, and the additional time required for passenger and luggage transfers between flights.
It’s worth noting that the above timings may vary if one of the flights in the hypothetical itineraries is operated by a different airline.
It’s important to note that MCT can vary significantly between different airlines and airports. This diversity can have several implications:
The Implications of Varying MCT Rules
It’s important to note that MCT can vary significantly between different airlines and airports. This diversity can have several implications:
- Dealing with Varying MCTs: Creating global flight schedules can be a complex undertaking due to the differences in MCTs. Airlines must carefully consider these variations when collaborating with other airlines or planning multi-leg journeys.
- Passenger Challenges: Passengers may encounter difficulties in navigating these diverse regulations, particularly when traveling internationally or through unfamiliar airports. Further, a short MCT can significantly increase the risk of missed connections, lost or delayed baggage if a passenger’s incoming flight experiences a delay.
