Missed a Connecting Flight? What the Airline Owes You and How to Reset Your Ground Plans

What happens if you miss a connecting flight?

The first minutes matter more than the rules. A missed connection is a queueing problem: the airline has a fixed number of seats on the next departures, and the passengers who reach a counter or an app screen first get the better options.

This guide has a clear order. It starts with what to do at the gate, explains why the ticket structure is the deciding factor, sets out what Canadian and European rules require when a delay is the airline's responsibility, says what US rules do and do not provide, and finishes with the part most articles skip: resetting a pre-booked ground transfer so a driver is not waiting for a flight you are no longer on.

It is not legal advice. Rules change and individual cases turn on details, so read the official pages linked below for your situation.

What should you do in the first 15 minutes?

Do these in order, and do them while walking to the nearest rebooking point.

1. Keep your boarding passes and bag tags. You will need them for any claim.
2. Open the airline app. Some carriers rebook automatically and show alternatives on screen. If the app has already put you on a flight, accept it before it fills.
3. Go to the transfer or customer service desk for your carrier, not the departure gate of the missed flight, unless an agent is still there.
4. Ask for the airline to protect you on the first available flight, including those operated by a partner airline.
5. Ask whether your bag is checked through. If you were issued a through tag, your bag follows your new routing. If not, you collect and recheck it.
6. Ask about meals and a hotel before you leave the desk. Vouchers are easier to obtain at the desk than by claim.
7. Tell whoever is collecting you about the change, once you know your new arrival time.

If you are at a US airport, you may also need to clear customs, collect bags and pass security again before your new flight. JFK's connections guide lays out this sequence for an international arrival continuing domestically, and the one-hour layover guide explains how the sequence eats time.

Why the ticket matters more than the airline

Everything else follows from one fact: was it one booking, or two?

• One ticket (one reservation). The airline sold you the connection. If you miss it because of a delay on its first flight, it must get you to your destination. Its minimum connection time was accepted at booking.
• Two tickets. You built the connection yourself. The second airline did not sell it, so a late first flight is, from its side, your problem.

Heathrow's connecting-flights page says the same thing in plain language: on a single ticket, the airline will usually quote a minimum connection time, and if you booked separate flights those minimums do not apply.

The consequence is simple and annoying. If you are travelling on two tickets, you should treat a tight connection as a gamble, leave a long gap, and consider buying the second flight as a refundable fare. If you are on one ticket, you have rights, and the next sections explain them.

What Canada requires when you are delayed or cancelled

The Canadian Transportation Agency's air passenger protection pages set out the rules for large airlines on flights to, from and within Canada. As of October 2026, the main points on its delays and cancellations page are:

• Rebooking. A large airline must rebook you free of charge on its next available flight, or a partner airline's, from your original airport.
• 48 hours. If the airline cannot rebook you within 48 hours of your original departure time, it must rebook you on any airline's flight, including from a nearby airport if available.
• 9 hours. If the situation was within the airline's control and it cannot rebook you within 9 hours, it must put you on an earlier flight of any other airline. That 9-hour rule does not apply when the cause is outside its control.
• Refund. If rebooking no longer meets your travel needs and the cause was within the airline's control, you are entitled to a refund of the unused portion of the ticket.
• Compensation. Only when all of these apply: the situation was entirely within the airline's control and not required for safety; you were told 14 days or less before departure; you reached your final destination 3 or more hours late; and you filed a written claim within one year.

The amounts for large airlines:

Compensation must be paid in money, with vouchers allowed only under specific conditions that include your written confirmation. The agency's page states that missed connections are not addressed specifically on that page, so confirm how a connection on your ticket counts before relying on the table.

What the EU requires: Regulation 261

The EU's Your Europe passenger rights page summarises its rules. For a flight where EU rules apply:

• Delay of 3 hours or more at the final destination can qualify for compensation, unless extraordinary circumstances caused it.
• Amounts. €250 for flights up to 1,500 km; €400 for flights over 1,500 km within the EU and for other flights of 1,500 to 3,500 km; and, for flights over 3,500 km, €300 or €600 depending on the length of the delay and the route, as the page sets out. If you are re-routed and still arrive late, the amount may be reduced by 50%.
• Missed connections on a single booking qualify if EU rules apply and you reach your final destination more than 3 hours late.
• Where you are not entitled. The page says you are not entitled to compensation if you miss your connecting flight due to delays at security checks, or because you did not reach the gate on time.
• Care. Airlines should provide assistance free of charge while you wait: refreshments, meals, a hotel if you are rebooked to the next day, transport to the accommodation and two calls or messages. Keep receipts if you pay yourself.
• Long departure delays. A departure delay of 5 hours or more gives you the option of a refund and, if you have a connection, a return to the departure airport.

The exclusion for security-check delays is important for one specific case: if your first flight landed on time but an immigration or security queue made you late, the airline is unlikely to owe compensation. If the first flight itself was late, it is a different story.

What US rules provide and do not provide

I could not open the US Department of Transportation's own pages when I checked in October 2026, because the site blocked automated access, so I am keeping this section general.

In broad terms, US federal rules do not set cash compensation for a delay or a missed connection. They do require refunds in certain situations when an airline cancels or significantly changes a flight and you decline the alternative. Beyond that, what you receive depends on the airline's own customer-service commitments and its contract of carriage. Check the carrier's published policy and the Department of Transportation's consumer pages for the thresholds that apply to your date.

If you are flying between Canada and the United States, Canadian rules apply on a flight to or from Canada, as the agency states for flights "to, from, and within Canada, including connecting flights."

Missed because of customs or security: how long does customs take?

This is one of the most searched questions after a missed connection, and the honest answer is that no official source publishes a reliable typical time.

What the US border agency does offer:

• A single page, Advisories and Wait Times, which points to its wait-time tools for airports and borders.
• Mobile Passport Control, available at 63 sites to US citizens, lawful permanent residents, Canadian B1/B2 visitors and returning Visa Waiver Program travellers with an approved ESTA. Travellers submit their details in the app, up to 12 people per submission, and use the MPC line, where the agency says to "expect a shorter wait."

For planning, treat the border as the largest uncertainty. A good habit is to leave generous time after an international arrival and plan any onward connection with that margin in mind. No official source gives a typical figure, so none is quoted here.

How do you reset your ground transport?

If someone is collecting you, or you have booked a car, tell them the new flight number and arrival time as soon as you know them, and ask them to confirm. A booking that is attached to your original flight will not automatically follow you to a different one on a different airline.

For Onroutz.ca bookings, the airport pickup is tracked against your flight, and the usual waiting time starts from the actual landing. When you change flights, give the desk the new flight number so it can be tracked instead. The guide to how private airport transfers work explains the meeting-point and waiting-time basics, and the airport transfers service page covers the options.

Re-timing is easier than most people expect, but it does have a limit. If you land in the small hours, tell the desk early, because a driver cannot be conjured at the last minute. If you now arrive in a different city, the booking is a new route, not a change, and a fresh fare is shown in the booker.

Check your fixed fare

If you need a car for the rest of the day instead of a simple pickup, an hourly booking with a driver can cover a long wait between flights. The personal driver service describes how that works.

What to claim, and what to keep

• Receipts for meals, transport, a hotel and any phone use.
• Boarding passes, bag tags and the original itinerary, plus a screenshot of the airline's message showing the new flight.
• The reason given for the disruption, in writing if you can. Whether the cause was within the airline's control decides compensation in both Canada and the EU.
• The time you reached your final destination, which is the clock for compensation. Photograph the arrivals board or save the app's arrival time.
• A written claim. In Canada, the claim to the airline must be filed within one year.

Claims are the airline's to answer first. Only after it refuses or ignores you do you go to a regulator.

Mistakes that cost travellers money

• Leaving the secure area before you have a new boarding pass.
• Accepting a refund when you wanted to travel, which ends the airline's duty to get you there.
• Booking separate tickets for a tight connection, which removes the protection of one reservation.
• Missing a connection because of a self-inflicted delay, such as arriving late at the gate. In the EU, that is not compensated.
• Forgetting to tell the driver. A pickup attached to the original flight needs a change from you.
• Assuming one region's rules apply everywhere. The flight's route decides which rules apply, so check that before you claim.
