- Most airlines don't offer cheaper airfare at the airport. Airlines like Southwest give their customers the cheapest flight directly on their site, while you might be able to find a good deal on American, Delta, and United via sites like Kayak or Google Flights.
- If a person does go to the airport in an attempt to buy a last-minute plane ticket, they may find the ticket prices to be immensely higher than if they were to book online. Ultimately, there are no advantages to buying tickets directly at the airport.
- Airlines would rather overfill and bump people to later flights than sell empty seats at the last minute. And there aren't very many empty seats, since they can adjust prices in the weeks before the flight to make sure it fills up long before it flies.
