Whether you like the Boeing 737 MAX or not, there is no denying the type’s scale of activity. Only the MAX 8 and MAX 9 variants are used (the MAX 7 and MAX 10 are still to come). Based on examining every service using Cirium data, they have an average of about 2,900 daily departures in July (double for both ways). Southwest Airlines, Ryanair, United Airlines, Gol, and Aeromexico have the most flights.
