American is adding 3 new longer-range routes from New York LaGuardia. They'll fly only once a week because of this rule.

American Airlines will launch new longer-haul routes from LaGuardia Airport, targeting leisure travelers, with flights to Bozeman, Kalispell, and Calgary, commencing June 2025. This provision stems from LaGuardia's 'perimeter rule' waiver on Saturdays, allowing flights over 1,500 miles to operate. Despite the advantage, the Saturday-only schedule poses challenges due to lower demand, mirroring previous struggles faced by airlines like Delta, who have had to cut routes because of this limitation.

The 'perimeter rule' at LaGuardia restricts flights to 1,500 miles from Sunday to Friday, forcing airlines to reschedule longer routes to other airports like Newark and JFK. However, on Saturdays, airlines can take advantage of this waiver, allowing them to cater to leisure travelers looking to fly destinations like Montana and Calgary. American Airlines will use a Boeing 737 Max for these flights, all operating approximately 2,000 miles, showcasing the importance of strategic route planning under strict airport regulations.
