Many resort trips involve a connection: a regional flight to a hub, then a longer leg to Cancun, Punta Cana, Montego Bay or Aruba. The time between those flights is one of the few parts of the journey you can plan, and it is easy to get wrong in both directions. Too short and a late first flight can leave you stranded. Too long and you lose a day of the holiday and pay for the wait in tiredness. This guide explains how to read the connection time on your itinerary and how customs, terminals and bags change the numbers.
What a minimum connection time is
Every airport publishes minimum connection times in airline booking systems. They set the shortest gap the system will sell between two flights, and they vary by airport, by whether you change terminals and by whether the trip is domestic or international. If you buy a single ticket, the system will not normally let you book a connection shorter than that minimum.
The key word is minimum. It assumes that the first flight lands on time, that your gate is reasonably close and that you do not need to do anything but walk. It does not promise that you will board comfortably. On a holiday itinerary with a family, young children or a long walk, use the minimum as a floor and add time on top.
Why international arrivals take longer
The longest connection delays tend to come when your first flight arrives from abroad and your second leaves for a domestic destination. In the United States, passengers arriving from another country typically pass through border inspection at their first port of entry. They then collect checked bags, clear customs and recheck the bags for the onward flight, and some airports require a further security screening. Each step can involve queues, and the total depends on how many flights landed together.
The reverse direction is simpler: a domestic first flight into a hub, followed by an international departure, usually needs only a walk between gates, although a terminal change can add time. If your itinerary combines a US hub with a Caribbean or Mexican resort, check each leg for which direction has the border step.
When you arrive in Mexico or a Caribbean country on a direct flight, expect immigration, a bag claim and a customs inspection at the airport. Mexico uses a system in which arriving passengers press a button and a light decides whether a baggage check is needed. These steps all come before the transfer to your resort, and they set how long your driver or shuttle should wait for you. Our explanation of how included airport transfers work covers the wait times to build into a transfer booking.
Terminal changes and airport size
A large hub can require a train or bus between terminals, or a long walk, and some airports require you to leave the secure area and pass through security again when you change terminals or carriers. The booking site usually flags a terminal change, but it may not warn you when the walk is long or when a shuttle runs only at intervals. Look at the airport map for both gates before you choose a short connection.
One ticket or two
If both flights are on a single booking, the airline is responsible for rebooking you when a delay causes a missed connection. If you buy two separate tickets, a late first flight is your problem to solve, and the second airline can treat you as a no-show. The practical effect is that you need a much longer buffer when tickets are separate. Our guide on separate tickets and one booking explains the trade-off in detail, and what to do after a missed connection covers the recovery steps.
A way to choose a buffer
No single number fits every airport, but a method does. Start with the airline’s minimum, then add time for each of these that applies to your itinerary:
- Arriving from abroad into a country where you must clear customs and recheck bags.
- A terminal change or a long walk between gates.
- Travelling with children, luggage or limited mobility.
- A first flight in winter weather or at a hub that often has delays.
- The last flight of the day, where a miss means an overnight stay.
Also consider the other side of the choice. A very long layover in a hub can be cheaper, but it can also be a long wait in an airport. If the gap is more than a few hours, an airport lounge may be worth considering, and our guide to lounge access before a resort flight explains the options.
Protecting the rest of the trip
If a missed connection will cost you a resort night, call or message the property early, because many resorts can hold a room or adjust a transfer if they know your delay. Keep your reservation numbers and driver contact details where you can reach them from the airport. A policy that covers missed connections may help with extra costs; see our notes on what to check before you buy travel insurance.
Check the official details
Border procedures and airport layouts change, so check your airline’s page for the airports on your itinerary, the airport’s own website for terminal maps and the border agency’s guidance for the country where you will enter. In the United States, the Customs and Border Protection travel pages describe arrival procedures and the programs that can shorten them.
