Would I delay flights, when not showing up for part of the journey?

Would I delay flights, when not showing up for part of the journey? - Top view of miniature airplane placed on over gray world map with crop hand of anonymous person indicating direction representing travel concept

This is a hypothetical question.

Say you book a flight from A through B to C. For some reason or another, you choose not to board the last part of my trip. Would this create problems for other passengers?

When a checked in traveller does not show up for a flight, that flight is actually delayed – at least if he/she has baggage checked in. If he/she doesn't show up within a reasonable time, the crew will start off-loading the baggage, delaying the flight even further. In my experience, this process takes approximately 20 minutes (which may be very frustrating for other travellers, whom may have planes to catch at the next airport).

So, to recap:

  • If I don't show up for one part of the journey, will that delay those flights?
  • What if my luggage is short checked to point B (for example, when they need to be taken through customs) and you don't check them back in?
  • What if I only bring carry-on luggage?


There are some related questions below, but they focus on whether or not you as a traveller may face problems, whereas I am more interested in what problems it will cause for the airlines and other travellers.

It depends on the specific circumstances.

If you have checked luggage that has been loaded onto the plane, AND you're on a flight that requires Positive Passenger Bag Matching (PPBM - more on that below) then there will be a delay whilst they first try and page you, and then resort to removing your checked bags from the plane. Normally this would take 5-20 minutes, depending on the type of plane, the airline, and how closely they track where luggage is stored in the plane. Most airlines start this process ~10 minutes before departure, so any delay would normally be closer to 5-15 minutes.

If you do NOT have luggage, OR if you're on a flight that does not require PPBM, then you will likely NOT delay the flight at all. Most airlines have a cut-off time 10-15 minutes before the stated flight departure time, and if passengers are not at the gate at that time then their seat can be released and even given to another (standby) passenger if required. Depending on the exact situation some airlines may delay the flight by a few minutes whilst they page the passenger, but that's becoming more and more unlikely.

Now, back to PPBM. Positive Passenger Bag Match is a regulation introduced on most international flights and many domestic flights after the bombings of Pan Am Flight 103 over Lockerbie, Air India 182 over the Atlantic Ocean, and UTA Flight 772 over the Sahara Desert. In each case these bombings involved luggage for passengers that were not on board the flight.

PPBM regulates that a customer should not be able to cause their checked luggage to fly on a flight that they are not on. That's not to say that their luggage can't go on a different flight - it's just that the passenger themselves can't make that happen by, for example, failing to board the flight.

US domestic flights do NOT enforce PPBM as all checked luggage in the US is screened for explosives before being loaded on the plane.

Can you miss a flight on purpose?

While it may come as a surprise to incredibly conscientious travelers who typically arrive at the airport three hours prior to their scheduled departure time, some travelers do in fact miss flights on purpose. Though not common, this can be done as a way to score cheap flights.

Should you show up on time for a delayed flight?

Most airlines will tell you to show up on time anyway. One version of that guidance is found on JetBlue's website: "For delays, we suggest you arrive at the airport for the originally scheduled departure time. If conditions allow, the estimated departure time could be moved up.

What happens if your flight is delayed and you miss your connecting flight?

What happens if a flight is delayed and you miss your connection? If you miss your connection due to a delay, usually the airline is responsible for providing you with a replacement flight to your destination. They will have to book you on the earliest possible flight available.
