Missing Your Connecting Flight? Here’s What to Do Next

It was Christmas 2019, and I was sprinting through the Copenhagen airport with a bunch of strangers and a very sweaty winter coat, trying to catch a connecting flight I’d booked separately.

It started with a discount code. A family friend got me a deal on a Canadian airline, but the code wouldn’t work on the Copenhagen to Stockholm leg. So I booked Toronto to Copenhagen with the code and the second flight with SAS directly, and thought I’d gamed the system. I had given myself a 90-minute layover and no safety net.

On the morning of my flight, the sky was clear. By lunchtime, a blizzard was burying the city and every departure out of Pearson was delayed. Our plane then sat at the gate for 40 minutes waiting on late passengers, followed by a long crawl through the de-icing line. When the flight attendant told the 25 of us with connections that Air Canada passengers would simply be rebooked, I had to admit mine wasn’t an Air Canada ticket. I’ll never forget her face.

We landed 15 minutes before my connection was due to leave. When I got off the plane, I sprinted for the customer service desk; an agent told us the plane was already gone. But the board behind her said “BOARDING AT GATE B4.” So, rather than listen to her, I ran through the terminal, through passport control, reaching the gate with one minute to spare. I made it, only barely. And after all that stress, I learned an important lesson. So here’s what I wish I’d known, so you can learn from my mistakes.

Why Separate Tickets Are a Bad Idea (Even When They’re Cheaper)

I get the temptation. I had a discount code, and booking the second leg on its own felt like beating the system. Here’s what I didn’t understand: when you book on one ticket, you’re buying the flights and also a promise. If something goes wrong, the airline has to get you to your destination. When you book separately, that promise disappears.

1. Nobody owes you anything if you miss the connection.
Neither airline is responsible for the other’s delays. Mine was running late because of a blizzard, but SAS had no obligation to wait or rebook me, and Air Canada had no obligation to cover a flight on another airline’s ticket. On one ticket, a missed connection is the airline’s problem to fix. On two, it’s yours.

2. The savings can vanish in one bad day.
Rebooking would have cost me almost as much as the whole trip, at Christmas, at the last minute. If you save [$X] by booking separately but risk a [$Y] replacement fare, you’re gambling. Before you book, ask yourself whether you could comfortably absorb the worst case.

3. Your bags won’t follow you.
On a single ticket, bags are usually checked through to your final destination. On separate tickets, you typically have to collect them, clear passport control, find the next airline’s check-in, and drop them off again, all within your layover. That’s why I kept my bag. Check your layover against everything you’d have to do, not just the walk between gates.

4. Border control adds time and uncertainty.
In Copenhagen, I had to clear passport control mid-sprint. Depending on your route, separate tickets can mean extra immigration steps or document checks that don’t apply to a protected connection.

5. Missing one flight can wreck the rest of your trip.
If you’re a no-show for one leg, some airlines cancel your remaining flights, including your return. Check the fare rules, and call the airline if you’ve missed a segment.

6. Your passenger rights may not apply.
Compensation and care rules, like those in the EU and Canada, often apply only to a single booking. On separate tickets, you may have no claim at all.

If you’re still tempted, here’s how to do it more safely

• Leave a long layover. I’d say at least 4 hours, more in winter or at big airports.
• Fly in the day before if the trip is time-sensitive, such as a wedding or a cruise.
• Travel carry-on only.
• Check both airlines’ policies on tickets and baggage before booking.
• Know your backup plan (trains, buses, other flights) and what it would cost.
• Consider travel insurance and read what it covers for missed connections on separate bookings.

Winter Travel Tips: Plan for Things to Go Slowly

Winter changes the rules of travel. A clear morning can turn into a blizzard by lunch, and one delay at one airport can ripple across an entire route. I learned that the hard way, with a 90-minute layover and a sky that went from sunny to snowstorm in three hours. You can’t control the weather, but you can build in enough buffer, backup, and patience that a delay becomes an inconvenience instead of a crisis. Here’s what I’d do differently.

Before you go

• Fly in a day early for anything time-sensitive. Weddings, cruises, and big events are where winter delays hurt most.
• Book the earliest flight of the day. It’s the least likely to inherit someone else’s delay.
• Choose your connection city carefully. Hubs that handle snow well recover faster than ones that shut down.
• Buy travel insurance and check what it covers for weather delays and missed connections.
• Add buffer on both ends, including the ground trip to the airport, since roads and trains slow down too.

Packing

• Wear your bulkiest layers on the plane. It saves bag space (I learned the sweaty way).
• Keep essentials in your carry-on: medications, phone charger, a change of clothes, and snacks.
• Pack your own food if you have dietary restrictions. Airline meals and airport options may not work for you, and a long delay makes that a bigger problem.
• Bring a portable charger so you can rebook or check updates on your phone.

Tracking and alerts

• Check the weather at your departure city, your connection city, and your destination. A storm anywhere on the route can disrupt you.
• Turn on airline app notifications so you hear about changes before the airport board updates.
• Watch your inbound aircraft. If your plane is delayed arriving, your departure will be too.
• Check the morning of, then again before you leave for the airport.

If delays hit

• Expect delays from de-icing, snow clearing, and crowded runways, and plan for them rather than being surprised.
• Have a backup ready, like a train schedule, bus, or alternate flight, before you need it.
• Get in the rebooking line and call or use the app at the same time.
• Know your rights under your airline’s weather policy, which is often more limited than for mechanical delays.
• Stay kind. Staff are dealing with hundreds of stressed travellers, and politeness gets better results.

At your destination

• Wear the right shoes. Waterproof, with grip, is worth more than a fashionable boot.
• Allow extra time for getting around, since winter weather slows transit, taxis, and walking.
• Keep a buffer on your return trip, so a delay on the way home doesn’t cost you work or a connection.

If You’re Running Late Right Now

Ask your flight attendant first. Do it kindly, and don’t make it sound like blame. Mine checked where our gate was and whether the next flight was delayed too. Crew can often find out things you can’t. And if there are several people on the flight trying to make a close connection, they might ask all other passengers to let those connecting deboard the plane first.

Keep your carry-on with you. I declined the offer to check my bag to my final destination, and that decision is the reason I could board. Checked bags can’t be pulled quickly, and on separate tickets, they may not transfer at all.

Go straight to your gate, not the service desk. I was told my plane had already left. The board still said “Boarding,” so I ran. Departure screens are more reliable than a tired agent in a long line. Check the screen yourself before you accept “it’s gone.”

What to do if You’ve Already Missed Your Flight

Go to the airline’s desk right away, or call. Lines form fast. While you wait, call the airline or use their app. You may reach someone first. It might be worth purchasing the on-board wifi if this will help expedite the process when you get off the plane.

Know whose problem it is. This depends on how you booked:

Who rebooks you?	The airline, usually free	No one, you’re on your own
Cost to you	Typically nothing	Often a new fare or change fee
Bags	Usually checked through	You collect and recheck them
Your leverage	Strong	Weak

Know your passenger rights. Rules differ by region and airline. In the EU, for example, passengers on a single booking have specific rights when a delay causes a missed connection, though severe weather can limit compensation. Canada has its own passenger protection rules for flights to and from the country. These don’t help much on separate tickets.

Compare alternatives before paying. Have a backup ready. Mine was a Copenhagen to Stockholm train every few hours, which would have cost far less than a new flight, though it takes about 5 to 6 hours. Check trains, buses, and other airlines before buying a last-minute ticket.

Call ahead if you know you’ll miss it. If you’re stuck on a tarmac or in traffic, contact the airline before your flight leaves. A change made in advance is usually much cheaper than a new ticket, and a courtesy call sometimes gets the fee waived.

Be kind. The agent controls your options. The flight attendant who gave me her own dinner when my special meal turned out to be the one thing I couldn’t eat taught me that kindness travels both ways.

How to Avoid This in the First Place

Book connections on one ticket. This is the big one. I thought I’d gamed the system with a discount code, but I’d given up my safety net. If you must book separately, treat the connection as a separate trip and pad it with plenty of time.

Don’t book short layovers in winter. Ninety minutes looks fine in a booking engine, but winter weather, de-icing queues, and late-arriving passengers can add hours. Give yourself a buffer, especially in cities that get real winters.

Pack carry-on only. A few fewer outfits is worth it if it means making your flight. It’s also just good travel advice generally.

Check your airline’s app the morning of. I didn’t notice the blizzard until it was already outside the window. Check delays and weather before you leave, not after.

The Real Takeaway

Missing a flight is stressful, but it isn’t the end of the world. I arrived in Stockholm exhausted, dehydrated, and so relieved that everything after felt like a gift. Have a plan, ask politely, and help others when you can. Good karma is never a bad thing to have on your side.
