Data from Aviation analytics company Cirium shows that American Airlines offers the most seats of any airline this summer. Using schedule data for this month, they edge out Southwest Airlines as the largest carrier by the measure. Both American and Southwest have a heavily domestic-focused network, and don’t fly their seats as far as United Airlines (or Delta).
Overall domestic scheduled seats are up 6% year-over-year despite aircraft delivery delays, especially by Boeing. Seats are up 7.8% across the Atlantic this month with Delta just a hair’s breadth behind United Airlines.
