What this means
No major FAA airport delay event is currently reported for ONT. Operations look fairly normal.
Individual flights can still be delayed or cancelled when the airport looks fine. Check your airline for your actual flight.

Usually at this time
82%
of ONT departures left on time on a typical Monday, across 4,039 flights. Monday evening is one of ONT's rougher stretches historically.
Historical departure punctuality from U.S. Bureau of Transportation Statistics, June 2025 – May 2026. This is a separate measurement from anything above: the FAA's delay figures describe traffic-management actions taken today, and averaging the two together would produce a number that means nothing. A ground stop is still a ground stop on an airport's best weekday.
Flying out soon?
