A common questions Buddy and I see from travelers is simple: is a one-hour layover enough? The honest answer is — sometimes yes. Sometimes absolutely not.
Airlines sell one-hour connections every day. They are technically legal, yes. But the better question is: what happens if you miss your connecting flight?
Over the years — and more than 1.5 million miles flown — we’ve learned that layovers aren’t about what’s possible. They’re about risk, consequence, and how much stress you’re willing to accept.
Here’s how we think about it.
Domestic to Domestic
In good weather, one hour is the bare minimum for a domestic connection to a domestic destination.
At smaller airports, that’s often manageable if everything runs on time. But that’s a big “if.”
If your connecting airport is in snow country during winter, plan at least 90 minutes. De-icing delays and weather disruptions can quickly erase your margin.
At large hubs like Atlanta or Minneapolis, gates can be far apart. Even with trams and moving walkways, long distances matter. If your inbound flight is even slightly late, that one-hour cushion disappears fast.
Can you make it? Often yes. Will you enjoy making it? That depends on your risk tolerance. Buddy and I have a low tolerance for rushing through airports. We loathe adding more stress to our life.
Domestic to International (Outbound)
When connecting from a domestic flight to an international departure, you don’t go through passport control outbound. But international boarding usually begins 50 minutes to an hour before departure.
That changes the math. For domestic to international connections, we plan a minimum of two hours for good weather.
Why? Because if your inbound flight is delayed by 20 or 30 minutes, your margin is gone. You will normally arrive at a domestic terminal and will have to navigate to the international terminal, which can be a distance away, or even a satellite terminal you need to take a bus to. That will eat up a lot of time.
Missing your outbound international flight can cost you more than inconvenience — it can cost you a full vacation day, hotel reservations, tours, and carefully planned logistics. There may not be another international fight until the next day and depending on the time zone you are traveling to, that can be a significant delay.
If the price difference between a tight connection and a safer one is small, we almost always buy the margin. A few extra dollars for peace of mind is worth it.
International to Domestic (Returning to the U.S.)
This is where tight connections become risky.
When you return to the United States, you must:
- Deplane
- Clear passport control
- Wait for and collect your checked baggage
- Clear customs
- Re-check your bag
- Go through security again
That process eats up time because each one of those choke, or delay, points takes time, especially passport control if you don’t have Global Entry. That time varies depending on the airport, the day, and how many international flights have arrived.
At major hubs, we plan at least 2.5 hours for this type of connection.
We learned that lesson the hard way.
A Hard Lesson From Minneapolis
On a return trip from England, we flew from Newcastle to Paris, to Minneapolis, and finally to Louisville. A 30-minute air traffic control delay out of Paris caused us to land late in Minneapolis.
It wasn’t Delta’s fault. ATC controls all inbound and outbound traffic, and they are the final arbiter of departures and arrivals. The delay happened in Paris. But the truth is — we built too little margin into that connecting flight in Minneapolis. Partly our fault.
Even though we were seated near the front of the aircraft and were one of the first off, our gate was at the far end of the international concourse. Our connecting flight was on the domestic concourse, all the way down at the end of the C gates.
We moved quickly as we had to go through the passport and customs. We missed the tram. By the time we reached the gate, the boarding door had closed. We missed boarding by 3 or 4 minutes.
As soon as I saw the boarding door was closed, we immediately slowed down and accepted we missed our flight.
Panicking and confronting the gate agent wouldn’t reopen that door. It never does. So we shifted into problem-solving mode. Improvise, adapt, overcome.
We walked down to the nearest Delta agent, calmly and politely explained what happened, and voila, she was able to get us a seat on the next available (and last) flight that evening. The reality was we would either get home later that evening or the next day. We got lucky and got home to our dogs that evening.
If we had given ourselves more margin, we likely would have made our original flight comfortably. Delays happen. If you travel often enough, you may even have an overnight delay. What matters is how much buffer you build into your plan — and how you respond when things don’t go as planned.
International to International (Major European Hubs)
International-to-international connections at large hubs like Paris Charles de Gaulle or London Heathrow can also be surprisingly complex.
You may encounter:
- Long terminal transfers
- Additional security screening
- Remote stands requiring bus transfers
- Extensive walking distances
On another trip home from Newcastle via Paris, we almost missed our international flight.
Newcastle is a smaller airport and Air France operates regional jets from there. We were a few minutes late out of Newcastle. When we landed at Charles de Gaulle, we kept taxiing past the terminal until we were at the far end of the tarmac. I truly wondered where we were going.
When we parked I looked at my watch and realized our plane to Atlanta had started boarding as it was 50 minutes before departure. The buses finally came, we got in the first bus and headed to the terminal. Stopping for a couple airplanes along the way, the bus kept driving around the terminal until it finally reached our door. At this point I had 20 minutes left to board. We went up the escalator to the security checkpoint. That took another 10 minutes to get through. Now time was getting critical.
Those two factors erased nearly all of our layover margin.
We had to move quickly through a massive airport. Boarding was nearly complete when we arrived — but we made it. As soon as we saw they were still boarding (5 minutes left) and knew we had a confirmed seat, we slowed down immediately. Stress level dropped back to almost nothing.
Lesson learned: if you’re flying from a smaller European airport into a massive hub, factor in the possibility of a remote park and bus to the terminal and additional screening. That alone can consume 30 – 45 minutes you didn’t plan for.
How to Decide for Yourself
We’re not going to tell you exactly how long your layover should be. That’s your decision based on your trip, your comfort level, and your risk tolerance.
But before booking a tight connection, ask yourself three questions:
What are the consequences if I miss this connection?
Are you heading home? Or are you starting your vacation? Will you lose a hotel night or a prepaid tour? 💰 The consequences should drive how much margin you build in.
What are the realistic risks?
Winter weather? ❄️ A massive hub airport? International arrival procedures? Possible bus transfers or additional security? Every variable increases the risk of a tight connection not working out.
How much stress am I willing to accept?
Do you want to spend your flight watching the clock? ⏱️ Or would you rather sit at the gate with extra time, relaxed and ready?
A connection can be perfectly legal and still be a poor decision for your specific trip.
The Bottom Line
You can’t eliminate delays. But you can decide how much buffer you build into your travel day.
Buddy and I would rather sit comfortably at the gate with extra time than rush toward a closed boarding door. That extra hour at the gate is not wasted time — it’s insurance.
Plan your layovers the way a pilot plans a flight. Account for the variables, build in your margin, and give yourself room to handle the unexpected without it ruining your trip. If you plan thoughtfully, you’ll travel more confidently — and enjoy the journey as much as the destination. ✈️
Buddy agrees. He prefers the relaxed gate experience. More time to people-watch from the seat pocket, and people are funny!
