Data from aviation analytics company Cirium indicates that American Airlines offers the most seats of any airline this summer, surpassing Southwest Airlines as the largest carrier by this measure. Both airlines have a predominantly domestic network and do not fly their seats as far as United Airlines or Delta Air Lines.
Overall, domestic scheduled seats have increased by 6% year-over-year despite aircraft delivery delays, particularly from Boeing. Seats across the Atlantic have risen by 7.8% this month, with Delta trailing United Airlines closely. United maintains a larger presence across the Pacific.
Among domestic carriers, American Airlines leads in the number of seats flown domestically, followed closely by Southwest Airlines. Breeze Airways has shown rapid growth at 33.36%, expanding from a low base. Ultra-low-cost carriers Spirit Airlines, Frontier Airlines, and Sun Country Airlines have also experienced significant growth ranging from 21% to 36%. These carriers are attempting to spread higher costs over more seats.
