LOS ANGELES (CNS) — Signs are pointing toward a busy summer travel season as Ontario International Airport is reporting Tuesday a record number of international passengers in April.

There were more than 34,000 international air travelers who used Ontario International Airport in April, the most recorded in a single month in the airport’s history. It was an increase of 138% in April from a year ago. There were 500,000 domestic fliers at Ontario International Airport in April, 7.5% more than the same time last year.

Air passenger traffic rose 11.% in April to more than 530,000, adding to Ontario’s streak of double-digit increases.

“At a time when many California airports are struggling to restore international services, Ontario is experiencing strong growth and we expect that trend to continue in the coming months,” said Atif Elkadi, chief executive officer, Ontario International Airport Authority. “And while our terminals will continue to be busy, passengers can expect our popular and hassle-free experience with reasonably priced parking, easy access to terminals, clean and light-filled facilities, efficient security screening and first-rate dining options.”

Strong annual passenger totals were also reported by Ontario airport officials. The number of passengers increased 15% to 1.87 million, with domestic travelers 12.6% higher at 1.76 million and international passengers up 85.7% to more than 104,000.

Commercial freight and mail flights were down, decreasing 12.7% to 58,000 tons. Cargo volume declined nearly 10% to 243,000 tons compared to the same time last year, the first four months of the year, and is consistent with industry trends, according to airport officials.
