Imperial (IPL) → San Diego (SAN)
A reference for the Imperial County Airport to San Diego International Airport route. You'll find the operators on file, the great-circle geometry, the connecting options if no nonstop fits your dates, and a short profile of each endpoint airport.
The flight from Imperial (IPL) to San Diego (SAN) covers a great-circle distance of roughly 151 km (94 miles). Aircraft leave Imperial County Airport on an initial west heading. As US domestic sectors go, this one sits in the short-haul bracket: long enough that most carriers run it as its own dedicated rotation, but short enough to fit inside a single crew duty period.
SeaPort Airlines is the only carrier filing a scheduled IPL to SAN service in the dataset. Single-operator routes like this usually reflect a focus-city or hub-spoke relationship, or a market that's big enough to support one dedicated daily but not big enough to attract a second entrant yet.

At well under 1,500 km this is a regional sector. Carriers typically run narrow-body aircraft from the Airbus A320 family or the Boeing 737 series, with regional jets (Embraer E-Jet, CRJ) showing up on lower-frequency rotations. Block time runs around 55m. Expect a single-aisle cabin and no real meal service. A snack and a drink is usually all you get.
No obvious one-stop hubs appear on both ends of the network for this pair. Usually that means either the destination is a small spoke airport, or the only realistic itineraries route through a global super-hub well outside the region. The sections below point to the strongest candidates on each side.
Both endpoints sit inside the United States, so this counts as a domestic sector for fare-bucket, baggage, and carry-on purposes. Reservations on US carriers usually pick up the standard domestic checked-bag fee unless you hold elite status, and TSA PreCheck eligibility applies at the departure airport. See the United States routes index for other domestic pairs in the same network.
On the day of operation, the IPL to SAN direction lifts off heading west, then the great-circle track curves to compensate for the Earth's rotation. The return SAN to IPL sector heads east out of the gate, with 1 operators on file for the inbound side. Combine the two operator lists for a full picture of the city pair's competitive landscape.

Reading this route page
The operator list reflects scheduled-route filings in the OpenFlights dataset, not real-time availability. A carrier appearing here publishes a scheduled service on this sector. It isn't a live timetable, and the actual flight numbers, frequencies, and aircraft types shift season to season. For booking and current schedules, cross-reference the airline page above with the carrier's own website.
Distance here is the great-circle arc between the two airports' published coordinates. Real flight tracks wander off that line because of wind, ATC routings, oceanic crossings, and political airspace constraints. Block time is an estimate covering ground taxi, climb, cruise at typical jet speeds, and descent. Real block times shift with aircraft type, weather, and traffic, so treat the stat-strip number as a planning indicator rather than a published flight time.
