14 CFR 398.2 - Number and designation of hubs.
(1) A large hub is a place accounting for at least 1.00 percent of the total enplanements in the United States;
(2) A medium hub is a place accounting for at least 0.25 percent but less than 1.00 percent of the total enplanements in the United States; and
(3) A small hub is a place accounting for at least 0.05 percent but less than 0.25 percent of the total enplanements in the United States.
(2) In Alaska or when the nearest large or medium hub is more than 400 miles from the eligible place, the Department may instead require service to a small hub or nonhub.
(3) In some cases, the Department may require service to two hubs, of which at least one will be a large or medium hub. The Department will require service to two hubs if an eligible place has close commercial, geographic, and political ties to both hubs and if there is sufficient traffic from the eligible place to support two round trips a day to both hubs. If traffic is not sufficient, the Department may require one round trip a day to both hubs if the community requests such service.
(iii) The traffic levels to candidate hubs, as shown by traffic studies and origin and designation data;
(v) The size of candidate hubs. Large size will be a positive factor, but principally as substantiating the access and community-ties factors.
