What Our 30-Day Measurement Recorded at ONT

The figures in this section come from our own reception measurement of aircraft movements at Ontario International Airport, not from published schedules. Over 30 days, that measurement recorded an average of 6.2 movements per day at ONT, a figure that stands next to the average traffic level the airport carries in our data. The two describe different things: the traffic level is the class our data assigns the airport, the 6.2 is the count the measurement produced over those 30 days. The busiest window in those 30 days fell between 00:00 and 02:00, with one caveat: the measurement clock runs in UTC, not the local time at the airport, so it does not map directly onto the times shown on the arrivals and departures pages.

Airlines in Our ONT Data

Three airlines appear in our 30-day measurement at Ontario International Airport. Southwest Airlines leads the count with 60 logged movements, making it the carrier we picked up most often at ONT in that period; its flights have their own Southwest Airlines flight status page. Frontier Airlines follows with 26 movements, covered under Frontier Airlines flight status, and Delta Air Lines appears 18 times in the same 30 days, with Delta Air Lines flight status as its page on this site. These figures are counts from our own receivers, so they describe what we picked up at Ontario rather than each airline's full schedule at the airport. ONT itself is listed among the airports in the United States that we track.
