A short layover sounds simple, but the clock starts running the moment your first flight touches down. Forty minutes can feel like forever when everything goes smoothly, but if your aircraft parks at a distant gate or your incoming flight is delayed even a little, the stress hits fast.
Travelers often debate whether 40 minutes is enough time to connect to their next flight, especially at major airports like Detroit Metro Airport (DTW). The answer isn’t always black and white, but understanding how connections work can help you decide if this time frame works for you.
This guide breaks down what a 40-minute layover means, situations where it’s possible, when it’s risky, and tips to improve your chances. Whether you’re a frequent flyer or planning your first connecting flight, you’ll walk away feeling prepared.
What Is Considered a Short Layover?
A layover is the time you have between your arrival at one airport and your departure for the next flight. Most airlines consider 60 to 90 minutes to be a comfortable connection window. Anything under 45 minutes is generally seen as a short layover. At that point, every minute counts.
Airlines often define an MCT (Minimum Connection Time), which is the lowest amount of time they allow between flights when selling your ticket. If your itinerary is booked under one airline or partner carriers, the airline has decided it is theoretically possible. Still, real-world situations can change the experience.
Is 40 Minutes Enough Time?
A 40-minute layover is sometimes workable, particularly for flights connecting within the United States. However, there are many scenarios where 40 minutes isn’t realistic. The key is understanding what kind of connection you have.
Domestic to Domestic
Domestic connections are the most forgiving. You don’t need passport control or customs, so you’re simply moving from one gate to another. If both flights are on the same airline and in the same terminal, you might make it without rushing. At a compact airport, 40 minutes could feel tight but possible.
Domestic to International
Here, things get tougher. International departures often require extra steps, such as security checks or document verification. If you’re changing terminals, the risk grows even more. In most situations, a 40-minute domestic-to-international connection is too tight.
International to Domestic
This is where 40 minutes almost never works. You’ll need to go through immigration, collect your luggage, clear customs, possibly recheck your bags, and then pass through security again. Even at smaller airports, these steps take time. Because of this, 40 minutes isn’t recommended.

What Affects Whether You’ll Make It?
Several factors influence how smoothly a short layover goes. Some are within your control, others are purely luck.
Airport Size and Gate Distance
Big airports can feel like small cities. Detroit Metro Airport (DTW) has two main terminals. If both of your flights are in the McNamara Terminal, your chance of making the connection increases. However, if you need to switch between terminals, you’ll need extra time.
Same Airline or Partner
If your flights are on the same airline, odds are better. Airlines generally plan flight schedules so connections happen within the same terminal, which saves valuable minutes. When switching airlines, you may be forced into long walks or shuttle rides, eating into your time.
Checked Bags vs Carry-On
Checked baggage adds risk. Bags might get delayed when transferring, especially during busy travel periods. With only carry-on luggage, you move faster and don’t rely on baggage handlers.
Time of Day
Morning flights often run on schedule, but afternoon and evening flights accumulate delays. Weather issues, crew timing, and runway congestion can cause even minor delays that cost you your connection.
Security and Immigration
International arrivals add more steps. Even if your first plane lands on time, passport control lines may not cooperate.
Is a 40-Minute Layover Enough at DTW?
Detroit Metro Airport is relatively efficient. McNamara Terminal, home to Delta and its partners, has a train running within the concourse for quick movement. If both flights are in this terminal, 40 minutes can be manageable, especially domestically.
However, if you need to move between McNamara Terminal and the North Terminal, it’s often too tight. You’ll need a shuttle, and it only takes one delay to make things complicated.
DTW does a good job with signage and has friendly staff, but even the best conditions don’t guarantee success.

What If You Miss Your Connection?
Missing a connection isn’t the end of the world. If your flights are booked on one ticket, the airline usually rebooks you at no cost. This process depends on seat availability, so you may spend time waiting at the airport. If you booked separate tickets, you’re responsible for purchasing a new flight.
Airlines usually rebook based on the next available flight, which may not be ideal during peak travel times. Make sure to act fast and speak to an agent or use the airline app.
Tips to Make a Tight Layover Work
Even with a short connection, smart planning can help you move quickly. These tips give you a better chance at making your next flight.
Before Departure
- Choose a seat near the front of the plane
- Carry-on luggage only
- Download your boarding passes
- Wear comfortable shoes and avoid slowing yourself down
At the Airport
- Exit the aircraft promptly
- Know your connecting gate number in advance
- Follow the airport signage carefully
- Ask gate agents if your connection looks tight
Optional Programs
- TSA PreCheck
- Global Entry
These can save time, especially at larger airports.
When You Should Avoid a 40-Minute Layover
There are times when a 40-minute layover will make your trip far more stressful than necessary.
- International arrivals
- Terminal changes
- Winter travel when weather delays are common
- Traveling with young children
- Moving with elderly passengers
- Using checked bags
- Holiday travel rush
If any apply, consider giving yourself more time.
Better Alternatives to Short Layovers
While a 40-minute layover can be done, it’s not usually ideal. Here are more realistic options.
- Book a 60 to 90 minute layover
- Stay overnight if arriving late
- Choose a nonstop flight if possible
- Use a reliable ground transportation service to reduce stress
Travel shouldn’t feel like a race. Adding even 20-30 extra minutes can change the entire tone of your journey.
The Case for Private Transportation
If your concern is catching your next flight from another airport or city, private transportation offers a calmer option. Instead of rushing through terminals or worrying about luggage delays, you have a direct ride where you’re in control of timing. It can save precious minutes and gives you peace of mind during busy travel seasons.
Private transportation works especially well for corporate travel, group travel, and families trying to avoid stressful airport experiences.
