September passenger counts are now out from McCarran International Airport. Traffic soared up by 6.8% from the same month a year ago to more than 4.3 million. This marks 7 months in 2019 with the airport having more than 4 million passengers, and 12 consecutive months of YoY growth in air traffic. To date, 2019 has seen a 3.4% increase in arriving and departing passengers.

Digging in a little deeper, international traffic actually fell by 3.6% in September, while domestic carriers were up 7.5% for the month. International passenger growth has only seen slight growth for the year to date.

Looking at the top domestic carriers, Southwest is down 1.9% for the month, tracking a trend it has seen all year. Spirit posted yet another month of explosive growth, which has allowed it to leapfrog other carriers in the last year to take the number 2 spot for domestic air traffic.
