A connecting itinerary isn’t just slower than a nonstop — it multiplies the ways your trip can go wrong. Understanding that math is the key to deciding when a stop is worth the savings.
Why a stop is riskier than it looks
A connection adds two distinct risks. First, each leg is its own chance to be delayed or cancelled — two flights, two rolls of the dice. Second, and bigger, is the misconnect: if your first leg lands late, you can miss the second even though it departed perfectly on time.
The compounding is real. Two legs that are each 85% likely to go smoothly don’t give you an 85% trip — they give you closer to 72%, before you even add the risk of a tight connection. The cheapest connections tend to pair the tightest layovers, which is the worst of both worlds.
When a connection is worth it
- There’s no nonstop on the route (most long-haul and smaller-city travel).
- The savings are large, and you’ve deliberately built in a long buffer.
- You can connect early in the day, leaving same-day recovery options if a leg slips.
How to de-risk a connection
- One ticket, one airline. If you misconnect, they owe you the next flight; separate tickets don’t.
- A generous layover — see how much you need.
- A reliable connecting hub, especially out of weather season — check the airport’s record and connection minimums.
- Morning departures, before delays compound through the day.
