San Diego airport transit 2026 became more useful in September when MTS expanded Route 992. The airport bus now runs every 15 minutes throughout the day and into late evening hours.
Service continues until about 1 a.m. daily. That gives travelers more options after late flights, evening events, and long travel days.
Route 992 connects San Diego International Airport with Downtown San Diego. It also serves Santa Fe Depot, one of the region’s most important transit hubs.
The change is useful for visitors who want to avoid airport parking or a rideshare. It also helps airport employees who work early or late shifts.
This guide explains the new schedule, how to connect with other transit services, and what travelers should know before choosing the bus for an airport trip.
What Changed With San Diego Airport Transit in 2026
MTS and SANDAG introduced the expanded Route 992 schedule on September 6, 2026. The change added more evening and late-night trips.
Before the update, service frequency changed later in the day. The new schedule keeps buses running every 15 minutes until the end of service.
MTS currently lists Route 992 operating from about 4:30 a.m. until 1 a.m. each day. Travelers should still check the live schedule before leaving because individual trip times can change.
The improvement is part of a larger regional effort to create better connections to San Diego International Airport.
Route 992 Connects Downtown Directly With the Airport
Route 992 provides direct bus service between Downtown San Diego and both airport terminals. The airport stops sit on the elevated terminal platform.
MTS estimates that the trip between Santa Fe Depot and the airport takes about 15 minutes under normal conditions.
Traffic can still affect travel time. Leave a larger buffer when catching a flight, especially during weekday traffic or major events.
The route also uses buses with luggage racks and wider doors. Those features make boarding easier for travelers carrying suitcases.
15-Minute Service Makes Late Flights Easier to Plan
The biggest 2026 improvement is consistency. A bus scheduled every 15 minutes is easier to plan around than a route with long gaps late at night.
That matters after an evening arrival. A delayed flight can make a tight transit connection stressful when buses run infrequently.
The expanded schedule gives travelers more chances to leave the airport without immediately choosing a taxi or rideshare.
Still, the final buses do not wait for delayed flights. If your plane lands close to the end of service, check current departures before collecting luggage.
Travelers with very early departures should do the same. Service begins around 4:30 a.m., so a bus may not work for every early-morning flight.
A simple rule works best: compare the first or last Route 992 trip with the time you actually need to be inside the terminal.
Fare, Luggage and Boarding Are Straightforward
MTS currently lists the regular adult fare at $3 for a one-way trip. Reduced fares may be available for eligible riders.
Use the current MTS fare page before travel because prices and payment rules can change.
Route 992 buses include luggage storage. Keep smaller personal items with you when possible and avoid blocking the aisle with large bags.
Allow extra boarding time if you travel with several suitcases, children, mobility equipment, or oversized items.
The bus stops at both airport terminals. Check your airline and terminal before leaving Downtown so you know where to exit.
San Diego International Airport continues to change as work moves forward on the new Terminal 1. The first phase opened in 2025, while another phase remains under construction toward 2028.
That construction can affect roadway patterns near the terminals. Follow current airport signs rather than relying only on an older map.
Santa Fe Depot Makes Route 992 Useful Beyond Downtown
Route 992 becomes more useful because it connects with Santa Fe Depot. The station gives travelers access to several local and regional transit options.
MTS says passengers can connect there with all three San Diego Trolley lines, Rapid bus services, COASTER trains, and Amtrak.
This means a traveler does not always need to stay in Downtown for Route 992 to make sense.
Someone arriving from North County can take the COASTER toward Santa Fe Depot and transfer to the airport bus. A visitor arriving by Amtrak can use a similar connection.
Trolley riders can also reach Downtown and transfer for the final airport segment.
Plan the Connection, Not Just the Airport Bus
A 15-minute airport bus is helpful only if the first part of your trip also works.
Check the schedule for every connection. COASTER and Amtrak service does not run at the same frequency as Downtown buses.
Late-night travelers should pay special attention to the last train or Trolley trip needed after returning from the airport.
Build transfer time into the itinerary. A five-minute connection may look possible on paper but become stressful with luggage.
Santa Fe Depot is also large enough that first-time visitors may need a few minutes to find the correct exit and bus stop.
When heading toward the airport, MTS lists a convenient Route 992 stop near Kettner Boulevard and West Broadway, across from Santa Fe Depot.
Check the current stop information before travel because road work or special events can temporarily change boarding locations.
How to Use the Airport Bus Without Creating a Stressful Travel Day
Public transit works best when travelers leave enough time for small delays. Airport trips should have more buffer than an ordinary commute.
Start with your airline’s recommended arrival time. Then work backward from that point.
Add the expected bus trip, transfer time, and a reasonable delay allowance. Include extra time if you need to check luggage.
Visitors staying Downtown have the simplest Route 992 trip. Travelers coming from other parts of San Diego County need to check the full route.
A North County traveler may combine rail with Route 992. Someone staying near a Trolley station may use rail for most of the journey and transfer Downtown.
Another airport option is the San Diego Flyer, which connects the airport with the Old Town Transit Center. The best choice depends on where the trip starts.
Future Airport Transit Plans Go Beyond Route 992
Route 992 is the transit option available now. SANDAG is also studying larger airport connections for the future.
The agency completed an Airport Transit Connection study update in 2026. It is considering several Rapid bus and rail ideas.
Possible Rapid services could connect the airport with Downtown, Old Town, and Shelter Island. SANDAG is also studying transit-priority features that could help buses move more reliably through traffic.
Rail planning has narrowed from a much larger list of concepts. Current study work includes automated people mover and Trolley options.
Those ideas remain in planning. Travelers should not confuse them with a service that already exists.
Do Not Confuse Future Rail Plans With Today’s Airport Service
San Diego has discussed a direct rail connection to the airport for years. That can make current transit information confusing.
For a trip in 2026, Route 992 is a real operating service. Future Rapid and rail projects remain planning concepts.
SANDAG says funding for future phases has not yet been fully determined. Environmental work and additional planning would also take time.
Travelers should therefore build today’s trip around services that currently operate.
Route 992 is one of those choices. Its new 15-minute evening frequency makes it more practical than it was before September 2026.
The Old Town airport shuttle can make more sense for some riders. Rail and Trolley connections may also help depending on the starting point.
The best option is the one that creates the fewest difficult transfers while still getting you to the airport early enough.
The San Diego airport transit 2026 update is useful because it improves a service travelers can use right now. Route 992 now runs every 15 minutes until about 1 a.m., giving Downtown passengers a stronger alternative to driving or rideshare trips.
The connection at Santa Fe Depot also makes the route useful for some travelers coming from other parts of San Diego County.
Still, transit requires planning. Check the live schedule. Confirm your terminal. Leave time for transfers. Do not schedule the final possible bus when missing a flight would create a major problem.
San Diego’s long-term airport transit plans may eventually create even more options. For now, the improved Route 992 offers a simple and practical connection between Downtown and San Diego International Airport.
