Tech outage snarls ticketing at San Diego International Airport

Passengers at San Diego International Airport faced long lines and crowded check-in areas on Tuesday morning after a technical problem disrupted ticketing systems and slowed passenger processing across both terminals.

Early-morning outage slows ticketing but flights continue

Reports from local and national outlets indicate that the disruption began in the early morning hours of September 22, 2026, when an information technology failure affected shared ticketing systems used by multiple airlines at San Diego International Airport. The problem did not halt flight operations, but it significantly reduced the ability of staff to check in travelers and issue boarding passes at normal speed.

Coverage from regional broadcasters and online news services describes queues forming quickly in Terminal 1 and Terminal 2, with lines for some carriers looping through the main ticketing halls and into adjacent public areas. Passengers checking in for early departures encountered the longest waits as the outage coincided with one of the airport’s busiest morning periods.

According to publicly available information, the airport remained open throughout the incident, and aircraft continued to arrive and depart. Flight status boards and airline schedules showed most flights operating, although some departures experienced modest delays as passengers made their way through the slowed ticketing process.

Several outlets note that the affected systems were part of a common ticketing and check-in platform shared by multiple airlines, which amplified the impact across the two-terminal facility. The precise technical cause of the outage had not yet been detailed in public reports by early Wednesday.

Manual workarounds and crowded terminals

As electronic systems faltered, airport and airline staff turned to manual workarounds to keep travelers moving. Regional transportation coverage describes staff using tablets and printed paper tickets to process check-ins by hand, a slower method that nonetheless allowed boarding to continue and helped reduce the risk of widespread cancellations.

Images and video shared by local media show dense crowds in both terminals, with check-in lines extending toward entry doors and along terminal corridors. Some travelers reportedly waited significantly longer than usual to check bags or obtain boarding passes, though security screening and boarding gates remained open.

Travel-focused outlets report that, despite the congestion, there were no indications of extended ground stops at San Diego International Airport on September 22. Federal aviation data later showed only minor arrival and departure delays, generally in the range of 15 minutes or less, suggesting that the primary impact was inside the terminal rather than in the air traffic system.

Coverage from local public broadcasting notes that the shared ticketing system went down in the pre-dawn window and was gradually restored over the course of the morning. By midday, reports indicated that operations were stabilizing, although residual lines and processing backlogs remained in some check-in areas.

Guidance for travelers using San Diego International Airport

In updates relayed through media reports, the airport advised travelers to arrive earlier than usual and to monitor their flights directly through airline websites or mobile apps. The message emphasized that passengers should confirm departure times and gate information with their carrier before heading to the airport, especially while the technical issue was being resolved.

Published coverage also highlights longstanding guidance from San Diego International Airport for departing passengers to arrive at least two hours before domestic flights. Given the temporary slowdown in ticketing and check-in, several outlets noted that an even earlier arrival could help mitigate the risk of missing a departure during peak periods.

For travelers connecting through San Diego, publicly available information suggests that most flight schedules remained intact, but some passengers with short layovers may have faced tighter connections if boarding began later than planned. Travel news reports recommend that passengers with same-day connections build in extra time wherever possible or consider later onward flights when booking during periods of operational uncertainty.

Consumer travel coverage points to federal resources that explain what assistance airlines typically provide when delays are within their control, such as rebooking options or meal vouchers. In this case, early reporting focused primarily on terminal congestion and processing delays rather than large numbers of cancellations, and detailed accounts of individual airline policies in response to the outage had not been widely documented.

Recent growth and infrastructure context at SAN

The incident comes at a time of sustained growth and ongoing construction at San Diego International Airport. Publicly available passenger statistics indicate that the airport handled more than 25 million travelers in 2025, making it one of the busiest single-runway airports in the world. That growth has added pressure on terminal operations, particularly during popular morning and evening departure banks.

In recent years the airport has pursued a major redevelopment of Terminal 1 along with a range of roadway and transit improvements intended to improve access and passenger flow. Planning documents from regional transportation agencies describe expanded bus services and proposed rapid transit connections aimed at easing congestion around the airport’s compact bayside footprint.

News coverage of Tuesday’s outage notes that the disruption occurred just as the expanded Terminal 1 facilities and surrounding access projects are intended to provide more space and efficiency for travelers. While the IT failure was not linked to construction activities in available public reports, the episode highlights the sensitivity of high-volume terminals to software and systems reliability.

Observers in regional transportation reporting suggest that, as San Diego International Airport continues to grow, resilience in its information technology infrastructure will be critical to maintaining smooth passenger experiences. Even relatively brief outages in shared systems can cascade into hours of delays when large numbers of travelers converge on a limited check-in footprint.

What the outage means for upcoming travel

As of early September 23, 2026, real-time federal aviation data showed only minor arrival and departure delays at San Diego International Airport, indicating that the broader air traffic system was functioning close to normal levels. That status suggests that the most acute phase of the ticketing disruption has likely passed, even if some travelers experienced lingering crowds and slower check-in lines into Tuesday afternoon.

For travelers planning to pass through San Diego in the coming days, published information does not indicate ongoing systemic problems beyond the incident originally reported on September 22. However, travel news outlets continue to advise passengers to arrive early, monitor airline communications closely, and allow extra time to navigate construction-adjusted roadways and parking facilities around the airport.

The episode serves as a reminder that technical issues can arise even at airports where flight operations remain largely on schedule. For visitors and returning residents alike, building in additional time for check-in and security, especially during early morning and late afternoon peaks, can help reduce stress when unforeseen disruptions occur.

As investigations into the cause of the outage proceed, more detailed public information may emerge on how the shared ticketing systems failed and what safeguards will be added to prevent a repeat incident. For now, available evidence indicates that the disruption was concentrated in the terminals and that air service to and from San Diego continued with comparatively limited schedule impact.
