There’s an art to connecting flights. On the one hand, nobody wants to spend more time at the airport than they have to. On the other hand, layovers need to budget enough time between landings and takeoffs to ensure that you make it to your final destination on time.
How long you need to make a connecting flight depends on the airport. The sheer size of some airports can make the trek from one gate to another daunting. Take Denver International, the largest airport in the US and the second largest airport in the world, which measures 53 square miles. As one X user pointed out, that makes the Denver airport larger in land area than San Francisco.
