Do you have to pay for a carry on twice if you have a layover?

If your flight has a connection, bags will generally transfer from flight to flight and no additional fees will apply.



No, you do not have to pay for a carry-on bag twice for a layover, provided both flights are part of the same booking and ticket. When you purchase a ticket in 2026 that includes a carry-on allowance, that allowance covers your entire journey from the origin to the final destination, regardless of how many stops you have. If you are flying a budget airline (like Spirit or Ryanair) where you must pay for a carry-on, the fee you pay during booking is for the "trip," not per individual leg of the flight. The only exception to this rule is if you have booked two separate tickets on different airlines (e.g., flying London to Paris on EasyJet and then Paris to Rome on Vueling). In that case, you are technically ending one trip and starting another, and you would have to pay each airline's respective baggage fees. For a standard connecting flight with a layover on one itinerary, your baggage fees (and boarding passes) are handled once at the start of your journey.

If your flights were booked under one ticket, your bags will be checked through to your final destination. If your flights were booked under separate tickets, you will need to collect your bags and recheck them before your connecting flight.

Most domestic airlines allow passengers two carry-on items, depending on their fare type. For example, Southwest stands out among carriers for allowing passengers two free carry-on bags and two checked bags, regardless of fare type. That's also the case for Delta, American, Alaska and Hawaiian passengers.

While these terms are often used interchangeably, they are not the same thing. A layover is the time you spend at the airport between two flights. A connecting flight is the next flight in your itinerary that you're waiting at the airport to take.

On interline flights (where two airlines agree to handle passengers with multiple legs in their journey), your baggage will be transferred automatically. For international layovers in the US and Canada, you will have to collect and recheck your luggage independent of whether the flights are booked on the same airline.

You'll need to clear customs and immigration. Next, you'll recheck your luggage for the domestic flight. Finally, you'll need to go through Transportation Security Administration screening. This may include a physical inspection of your luggage and personal items with a metal detector or a full-body scan.

The main difference between a stopover and layover is length of time. Stopover rules vary by airline, but are essentially longer layovers — at least 24 hours in length. Layovers, meanwhile, are connections less than a day in length depending on if you're flying domestically or internationally.

MORE DETAILS

During domestic layovers, you are free to leave the airport. If your domestic layover is longer than one hour, you should expect to receive two boarding permits. If you want to check out local points of interest, make sure you get your second boarding pass and print it out before you leave.

The practice goes by a few different names, including skiplagging or hidden-city flying. Passengers disembark at their layover city, leaving an empty seat on their next flight, and save money in the process. But airlines are cracking down on the practice, claiming it breaches their rules and costs them revenue.

If your itinerary was purchased as one ticket (as in: you have only one itinerary and one confirmation number), and the connection time was too short and you miss the second (or third) flight, you can rest easy, no matter what happens. The airline will simply put you onto the next available flight, free of charge.

Basically, a layover is the time an airline gives you to change planes between flights. On a layover that's scheduled by the airline, you'll likely be traveling on the same ticket for every flight included in the itinerary, and you may have some time to kill at the airport.

What is a good connection time? Travel advisers say there's a lot to take into account when booking connecting flights, but a general rule of thumb is 60-90 minutes between domestic flights and at least two to three hours for international itineraries.
