Summer travel has a special talent for turning “It’ll be fine” into “Why is our gate suddenly in a different terminal?” If you’ve ever tried to herd a family (or just your own tired self) through a busy airport in June, you already know the truth: there isn’t one perfect layover length that works for every trip.
Instead of chasing a magic number of minutes, this guide gives you a simple framework for choosing connections that are less likely to ruin your day—especially during peak summer weeks when airports are crowded, lines can be longer, and gate changes happen. You’ll learn how to spot a complicated transfer before you book, build a realistic buffer, and set up a calm Plan B in case things go sideways.
The connection factors that matter more than the number of minutes
When people search “how long should a layover be,” what they usually need is confidence: Can we realistically make this? The answer depends less on the clock and more on the connection’s complexity.
Before you click “purchase,” check these trip-shapers:
- Same terminal vs. different terminal: A same-terminal connection can be straightforward; a terminal change can add walking time, wayfinding, and sometimes a train or shuttle.
- Domestic vs. international: Some international itineraries may involve additional steps (like document checks) and, depending on routing and airport procedures, you may encounter additional screening or formalities.
- One ticket vs. separate tickets: If your itinerary is on one booking, the airline has more options to help if a flight is delayed. With separate tickets, you may be treated like a no-show on the second flight if the first runs late.
- Checked bags and special items: Checking luggage, traveling with a car seat, or needing mobility assistance can change your pace and options.
In summer, add one more factor: crowds. Even when everything is “on time,” busy corridors and longer lines can quietly eat up your buffer.
Terminal transfers: how to spot a ‘hidden long walk’ before you book
Most missed connections aren’t caused by one dramatic problem—they’re caused by a series of small frictions: the gate is at the far end, signage is confusing, the train platform is one level down, the shuttle is “every few minutes,” and suddenly your comfortable plan is tight.
Use official information instead of guessing. A quick pre-booking check can save real stress later:
- Pull up the airport’s official terminal map or connection/transfer guide and identify the likely arrival and departure areas.
- Look for keywords like “inter-terminal train,” “shuttle bus,” “connector,” or “security checkpoint locations.”
- Scan your itinerary details for terminal letters/numbers when available (and remember they can change).
- Note any special steps mentioned for international arrivals, security screening, or document checks—these can be airport-dependent.
If you can’t quickly understand the route on an official map, treat that as a signal: choose a more forgiving connection, or pick an alternate connecting airport that looks simpler on paper.
A simple buffer strategy for domestic vs international trips (framework, not promises)
Because minimum connection times vary by airport, airline, and routing, it’s smarter to use a “buffer framework” than to rely on a universal minute count. Think in tiers: simple, moderate, and complex connections.
- Simple: Same terminal, no special steps, traveling light. You can consider a shorter buffer, but summer crowds still argue for some breathing room.
- Moderate: Potential terminal change, larger airport, traveling with kids/older relatives, or you want time for a restroom/water break without panic. Choose a more comfortable cushion.
- Complex: International segments, any itinerary that could involve additional screening or document checks, a big terminal transfer, or a last flight of the day. Give yourself the most buffer you can reasonably afford.
Two practical booking moves that often help: (1) avoid the last connection of the day when possible, and (2) prioritize earlier departures so delays don’t cascade into midnight decisions.

Your Plan B: what to screenshot and check in the airline app
Even with a smart buffer, summer travel can surprise you. A calm Plan B is less about “hacking” the airport and more about having your essentials ready so you can make good choices quickly.
Template: “Tight connection” one-page plan
- Before travel day: Download the airline app, sign in, and turn on notifications (gate changes, delays, rebooking prompts).
- Screenshot or save: Confirmation number, full itinerary, baggage info, and customer-service contact options inside the app.
- On landing: Check the next gate immediately, map the route, and decide fast: restroom now or after you reach the new gate area.
- If you’re running late: Go straight to the next gate first. If you’ll miss it, use the app to look at alternatives and ask airline staff what options exist for your ticket.
- Keep essentials accessible: ID, medications, chargers, a snack, and a small refillable bottle (fill after security). Organization helps—but don’t count on “seat tricks” to guarantee speed.
If a disruption turns into a bigger problem, it can also be helpful to know where to find general consumer information and how to document what happened (times, notifications, and receipts) for follow-up.
