American Airlines, Delta & United Will Begin Flying To These 24 Destinations This Year

American Airlines, Delta Air Lines, and United Airlines are the big three US carriers. Collectively, Cirium Diio data shows they will provide 61% of the country’s flights this year. They’ll operate almost two-thirds of domestic services and 42% of international flights. The trio will serve 491 airports globally, including 24 airports that did not see them last year—and, in most cases, never have.
