Flight Deals from Austin to San Diego from $134

The flight from Austin to San Diego is about 1,162 miles. A nonstop typically takes 2 hours 58 minutes, while the return to Austin takes 2 hours 55 minutes.

Methodology

Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

Yes, there are direct non-stop flights from Austin to San Diego, currently flown by Southwest Airlines and Alaska Airlines (operated by SkyWest), both running daily. Southwest offers the most service with 29 weekly departures spread across the day, while Alaska Airlines adds 21 weekly flights. These are the two carriers scheduled non-stop on the route this coming week.

Methodology

Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.

San Diego International Airport sits just three miles from downtown, so the trip into the city center is quick and straightforward. Rideshare and car service are the primary ground transportation options, with designated pickup zones outside both terminals, and taxis queue at transit islands on the arrivals level. MTS bus Route 992 runs from both terminals to downtown every 15 minutes on weekdays and every 30 minutes on weekends, and it connects to the Trolley, COASTER, and Amtrak at Santa Fe Depot — though the Trolley itself does not stop at the airport. Rental cars are collected at the off-site Consolidated Car Rental Center via a complimentary shuttle. Walking and biking are also viable thanks to a separated path to Little Italy and downtown.

Fares from Austin to San Diego are lowest in early February, around $210. February is the cheapest month overall, averaging $216, followed by January ($223) and October ($236). December is the most expensive month at about $270, and fares peak in late December at about $293. The yearly average is $247. Fares are adjusted to current market conditions.

Methodology

Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.

Book about 5 weeks before departure for the best fares from Austin to San Diego, around $218. Booking in the final days before the flight costs about $349, $131 more. Booking six months ahead runs about $359. Fares are adjusted to current market conditions.

Methodology

Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.

No overnight or red-eye flights operate on the Austin to San Diego route — there are no nonstop red-eyes, and no connecting itinerary has an overnight long leg either.

Methodology

Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

Southwest Airlines operates 29 weekly nonstop flights from Austin to San Diego, with daily service throughout the week. Alaska Airlines, operated by SkyWest Airlines, also flies this route nonstop with 21 weekly flights. Both carriers offer multiple daily departures, with Southwest's schedule spanning morning through late evening.

Methodology

Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.

Southwest Airlines follows at 70.5% on-time arrivals with a 0.1% cancellation rate, while Frontier Airlines trails at 60.0% on-time arrivals with a notably higher 5.4% cancellation rate.

Methodology

On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Southwest Airlines flies the most on Austin to San Diego, using Boeing 737-700 and other Boeing 737 family aircraft. Alaska Airlines, operated by SkyWest, also serves the route with Embraer E175 jets.

Methodology

Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.

Austin to San Diego is served non-stop by Southwest Airlines and Alaska Airlines, which operates under the Alaska brand with SkyWest flying the metal. Alaska Airlines belongs to the oneworld alliance, while Southwest is not part of any alliance. No other alliances serve this route non-stop, though other alliances may reach San Diego via connections.
