The time spent between changing of flights are called as layovers. Originally Answered: Why do planes have layovers? Mostly it is to do with destinations, airlines can't fly to every destination and from any destination. So they create hubs where passengers can gather and fill up a plane.
Layovers are a fundamental part of the "Hub and Spoke" model used by the global aviation industry to maximize efficiency and profitability. Instead of flying point-to-point between every possible pair of cities—which would be prohibitively expensive and result in many half-empty planes—airlines funnel passengers from smaller "spoke" cities into a central "hub" (like Atlanta, Dubai, or London Heathrow). At the hub, passengers are sorted onto connecting flights heading to their final destinations. This allows airlines to fill larger aircraft and offer more frequent service to more locations than would otherwise be possible. From an airport's perspective, layovers are lucrative because they increase "passenger throughput," driving revenue through landing fees and retail spending in the terminal. While often a minor inconvenience for travelers, layovers are what make the vast, interconnected web of modern air travel affordable and accessible in 2026, allowing you to reach almost any corner of the globe with only one or two stops.
During layovers, your aircraft may land at the connecting city to drop off and pick up new passengers. Sometimes, layovers require you to stay in the aircraft until it departs. Other times, you must get off the plane and head to a new aircraft at the airport.
Stopovers can range from as short as 24 hours to as long as 10 days, with no added cost to your airline ticket, depending on the program. To get the most out of a stopover, look for a program that offers other complimentary perks, too.
Is skiplagging illegal? No, but it's against most airlines' contracts of carriage or the rules people must follow to fly with the airline. American Airlines and Southwest Airlines both put skiplagging first on their lists of prohibited booking practices.
But skiplagging is controversial, and many airlines frown upon it – so much that it can be punishable by miles or status cancellations and even a lifetime ban from the airline.
For domestic to domestic layovers, you normally won't have to go through security again during your layover. However, for all international layovers, you will normally have to go through security again, but this will depend on individual airport policy.
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.
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.
While skiplagging isn't illegal, American Airlines filed a civil lawsuit earlier this month against Skiplagged.com, accusing the company of unauthorized and deceptive ticketing practices and tricking customers into believing they've gained access to a secret loophole.
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.
If you have an hour or more layover, you may have enough time to leave the airport and explore the surrounding area. Immigration and visa requirements: You may need a visa or other travel documents to enter the country, depending on your destination and nationality.
No matter what airline you're flying, if you have a connecting flight that arrives in the United States from an international destination, you'll need to pick up your bags and recheck them on your next flight.
It's not against the law. But it is a violation of the contract of carriage you entered into when you bought your ticket. Many people do this. It's called “Hidden City Ticketing” and it's a practice that should be used lightly because the airline will just ban you in the future if you do this too much.
For domestic flights in the U.S. minimum connection times range from 30 minutes to 2 hours, and for international connections, from 1 to 3 hours.
But skiplagging is controversial, and many airlines frown upon it — so much that it can be punishable by miles or status cancellations and even a lifetime ban from the airline.
It makes sense, because the practice saps revenue from them on two fronts: Not only do passengers underpay — potentially by hundreds of dollars per ticket — but the seat on the tossed leg also could have been sold to someone else. Most contracts of carriage from major airlines expressly forbid skiplagging as a result.
The practice can even result in airline-enforced penalties, such as adding those passengers to no-fly lists, asking them to buy full priced tickets to their true destinations or even removing frequent flier miles from their accounts. Even if airlines suspect you're skiplagging, punishments could be on the way.
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.
In commercial aviation, a red-eye flight refers to a flight that departs at night and arrives the next morning, especially when the total flight time is insufficient for passengers to get a full night's sleep. Nighttime at Venice Marco Polo Airport. The term derives from red eyes as a symptom of fatigue.
