While it is easier to get a direct flight than ever before, there is still a very good chance that you will have a layover the next time you fly. This is especially true if you are flying out of a relatively small city. This is done because airlines need to consolidate passengers onto one flight to a major connected airport in order to save money. These are four of the most commonly connected airports in the world.
O’Haire International Airport deals with more flight connections than any other airport in the world. Chicago is the perfect location for a connected airport because it is centrally located in the country. Airlines throughout the country can divert their passengers to Chicago without having to spent a lot of money on fuel. While there are dozens of airlines operating out of Chicago O’Haire, American and United handle the most flights at the busy airport.
If you are flying from the United States to Europe, then there is a very good chance that you will have to catch a connecting flight at Heathrow Airport in London. In addition to being the busiest airport in the world, London Heathrow is also the closest major European airport to the United States. Passengers heading overseas make a quick pit stop in London before catching a short flight to their final destination.
It is far easier for airlines to keep costs low if they operate out of a single hub city. They can transfer all of the passengers in small cities to the hub city before dropping them off at their final destination. This operating strategy is a major reason why you are likely to experience a layover at Dallas-Fort Worth International Airport at some point during your travels. This popular airport serves as the primary hub city for American Airlines.
Delta Air Lines uses the same hub city strategy out of Hartsfield-Jackson Airport in Atlanta. Passengers flying to or from a small city on the East Coast of the United States will get rerouted to Atlanta at the start of their trip. The Atlanta airport handled more than 107 million passengers last year, and 73 percent of them were on flights operated by Delta.
