Harry Reid International Airport welcomed a record number of passengers for the second straight month, the Clark County Department of Aviation reported Wednesday.

The airport serving Las Vegas saw 4.86 million passengers in July, a 17.2 percent increase over July 2021. The total beat the previous record of 4.69 million passengers set in June.

The record was no surprise since the Las Vegas Convention and Visitors Authority has said airline passenger capacity has been on a steady climb, with domestic air carriers adding flights and larger planes and international arrivals increasing after being grounded by the coronavirus pandemic. But whether the growth is sustainability has some experts taking a pause.
