New Seasonal San Diego–Loreto Nonstop Flights Start December 19

Source-checked update: This article brings together information checked against primary sources and independent reporting available at publication time. Full source links are listed at the end of the article.

Alaska Airlines has announced new seasonal nonstop service between San Diego International Airport and Loreto International Airport in Mexico. The flights are scheduled to begin on December 19, 2026, and tickets are already available, although the route is not operating yet.

What Happened

The new route will connect San Diego (SAN) directly with Loreto (LTO) during the winter and spring travel period. Service is scheduled to run through April 28, 2027.

Flights are planned twice weekly, on Wednesdays and Saturdays. The service will be operated with Embraer E175 aircraft by SkyWest Airlines on behalf of Alaska Airlines.

The announcement adds a new nonstop option for travelers planning to travel between the San Diego area and Loreto during the scheduled seasonal operating period. Alaska Airlines is currently selling tickets for the route, giving travelers the option to make bookings before the first flight date.

The timing is important: the flights are being offered for future travel, not as an already operating service. Travelers booking now should make sure their plans fall within the published December 19, 2026, through April 28, 2027, operating period.

What This Means for Travelers

For travelers departing from San Diego, the service is scheduled to provide a nonstop option to Loreto rather than requiring a connection. That may make the route relevant for passengers whose plans line up with the twice-weekly schedule.

The limited frequency also means flexibility will matter. With departures scheduled only on Wednesdays and Saturdays, travelers may need to arrange their trip around those operating days rather than selecting any day of the week. Return plans should be checked just as carefully, particularly for trips that cross the seasonal service window.

Because the route is seasonal, it should not be treated as a year-round connection. Travel dates after April 28, 2027, are outside the currently verified operating period, while dates before December 19, 2026, are before the scheduled launch.

The aircraft type is listed as the Embraer E175, operated by SkyWest Airlines. Travelers should review the booking details and airline information for the specific itinerary they are considering, including any applicable baggage, seating or connection terms. The verified announcement confirms the route, operating period and frequency, but does not establish additional service details for every booking.

For travelers already considering Loreto, the announcement provides an opportunity to compare a future nonstop itinerary from San Diego with other available travel arrangements. It does not, however, confirm that every date within the broader period will remain available at the same fare or with the same inventory.

What Travelers Should Do Now

Travelers interested in the new service can check Alaska Airlines directly for available itineraries and fares. Since tickets are available before the route begins, confirm that the selected departure and return dates fall within the scheduled operating period.

Check the day of the week carefully. The published schedule is twice weekly on Wednesdays and Saturdays, so a booking request for another day may not match the announced service pattern.

Before finalizing plans, review the itinerary for the operating carrier, aircraft information and any restrictions or conditions attached to the fare. Travelers should also confirm the latest schedule directly with Alaska Airlines before departure, since future airline schedules can be adjusted.

If the trip depends on a particular arrival or return date, leave enough flexibility to account for the limited frequency. Travelers connecting to other transportation or time-sensitive arrangements should verify that the scheduled flight days work with the rest of their plans.

Those planning travel outside December 19, 2026, through April 28, 2027, should not assume this seasonal route will be available. Check directly with the airline for alternatives and for any later updates to the service period.

What Is Confirmed

Alaska Airlines has announced seasonal nonstop service between San Diego International Airport and Loreto International Airport in Mexico.

The service is scheduled to begin December 19, 2026, and continue through April 28, 2027. Flights are planned twice weekly on Wednesdays and Saturdays, using Embraer E175 aircraft operated by SkyWest Airlines.

Tickets for the scheduled service are available through Alaska Airlines. The flights themselves are not yet operating; the verified service period begins on December 19, 2026.
