“We are eagerly anticipating the hustle and bustle of summer travel given high customer satisfaction for our gateway airport,” said Atif Elkadi, chief executive officer of the Ontario international Airport Authority. “Passengers can rest assured they will experience the same world-class, hassle-free experience that is our hallmark.”

Estimated passenger volumes by month are:

  • June: 657,297
  • July: 670,747
  • August: 651,467

In addition to the rise in popularity among air travelers for ONT, the increase is also attributable to new and expanded air service to 10 U.S. destinations since last summer including:

  • Denver (DEN) – Up to nine daily departures, including four daily flights from Southwest Airlines, three per day with United Airlines (up from two a day in summer 2023) and two a day on Frontier Airlines.
  • El Paso (ELP) – New service three times a week with Frontier Airlines beginning May 17.
  • Houston Hobby (HOU) – Daily service provided by Southwest Airlines.
  • Houston Intercontinental (IAH) – Eleven new weekly departures; four per week via Frontier Airlines starting May 17 and daily service on United Airlines starting May 23.
  • Nashville (BNA) – New daily service via Southwest Airlines beginning June 4.
  • Phoenix (PHX) – Up to 10 daily departures, including five with Southwest Airlines, four via American Airlines (up from three daily in summer 2023) and one offered by Frontier Airlines.
  • Portland, Ore. (PDX) – Up to five daily departures including three by Alaska Airlines (up from one a day in summer 2023), one with Frontier Airlines, which began in April, and Sunday-only service on Southwest Airlines.
  • Sacramento (SMF) – New daily service on Frontier Airlines beginning July 10 complementing up to five flights a day with Southwest Airlines.
  • Salt Lake City (SLC) – Four daily departures with three provided by Delta Air Lines and one with Frontier Airlines, which began in April.
  • Seattle (SEA) – As many as nine daily departures with four offered by Alaska Airlines, four on Delta Air Lines (up from 3 daily in summer 2023) and one with Frontier Airlines beginning May 16.

Airlines are offering more than 2.7 million seats from Memorial Day weekend through Labor Day with 80% expected to be occupied. The number of seats available this summer is more than 18% higher than summer a year ago.

“Southern California is a great place to be during the summer, and the Inland Empire, in particular, has become a premier international destination.  Ontario International is the ideal gateway for anyone to reach all that our dynamic region has to offer,” Elkadi said.

When arriving at ONT, passengers will also enjoy Mi Casa Cantina in Terminal 4 which offers original, authentic and innovative Mexican cuisine in a robust rollout of dining and shopping concessions since last year. Other recently added in-terminal concessions include Brewery X and the first-ever Top Golf Swing Suite in an airport.

Elkadi noted other customer-friendly aspects of the ONT experience such as curbside access for ride-share services, access to Aspire Executive Lounges, 3Sixty Duty-Free shopping, hourly and daily parking near passenger terminals and discounts on-airport parking when reservations are pre-booked.
