Harry Reid International Airport just logged another down month, with 4,642,207 arriving and departing travelers in March and a noticeable chill in overseas demand. The slower traffic leaves year-to-date totals trailing 2025's pace by roughly five percent and raises fresh questions about whether the soft patch will linger into the heart of spring travel season.
According to a press release from the Clark County Department of Aviation, March traffic slipped 4.2% from the 4,845,763 passengers recorded in March 2025. The same release shows LAS handling 12,544,018 passengers so far in 2026, a 5.14% decline compared with the first three months of 2025.
International Travel Takes the Biggest Hit
The sharpest pain is coming from abroad. International service was the weakest segment, with 265,836 international passengers in March, down about 15% from a year earlier. As reported by FOX5 Las Vegas, airport officials cautioned that the figures could still change as airline reporting and audits are finalized.
Who Gained, Who Lost
Domestic carriers, meanwhile, told a more mixed story. Southwest held onto its crown as the airport's top airline in March with 1,895,961 passengers, a modest 0.5% increase year over year. United posted a 7.7% bump and Frontier jumped 16.4%, according to the Clark County Department of Aviation carrier table. On the flip side, several international operators, including WestJet and Air Canada, saw steep drops in traffic, highlighting the split between sturdy domestic leisure demand and a softer overseas crowd.
What This Means for Las Vegas
One sluggish month on the books does not erase the big picture. Las Vegas still put up one of its strongest recent years in 2025, when Harry Reid International handled roughly 55 million passengers. The Las Vegas Review‑Journal noted that 2025 ranked as the airport's third highest annual total, a reminder that recent dips are coming off some pretty lofty peaks. Airlines, city tourism planners and local businesses will now be watching closely to see whether the international slowdown is a short-term wobble or the start of a longer trend that could reshape routing and capacity decisions heading into summer.
