A United Airlines flight traveling from San Francisco International Airport (SFO) to Shanghai Pudong International Airport (PVG) was forced into an emergency diversion to Los Angeles International Airport (LAX) on March 22, 2025, due to a pilot forgetting his passport.

The unusual incident aboard Flight UA198, operated with a Boeing 777-300ER, highlights critical concerns about passport control and verification procedures for flight crews.

Passengers aboard UA198 had been in the air approximately three hours when crew announced the unexpected diversion to LAX, where they subsequently waited for a replacement pilot.

Travelers received $15 meal vouchers from the airline as compensation during their unexpected stopover.

United Airlines apologized to passengers via a notification message, describing the issue as “crew-related” and promising prompt arrangements to resume travel to Shanghai.

The disruption caused substantial inconvenience and incurred significant financial costs for United, including additional fuel expenses and scheduling complications for the aircraft’s return flight.

Typically, international flight protocols established by agencies such as the U.S. Transportation Security Administration (TSA) mandate rigorous verification of passenger documentation.

However, inconsistencies appear when applying similar standards to flight crew members, leading to situations like this passport mishap.

This recent United Airlines incident represents the second passport-related disruption on the same San Francisco-Shanghai route within one week, according to travel industry reports. Previously, another pilot’s passport issue was discovered before takeoff, resulting in a multi-hour delay.

Such lapses are not isolated events. In December 2023, British passenger Craig Sturt traveled from London Heathrow Airport to New York’s JFK Airport without possessing either a ticket or passport.

Despite stringent security protocols outlined by the UK’s Department for Transport and Heathrow Airport’s established procedures, Sturt managed to board a British Airways Boeing 787 unnoticed. Authorities apprehended him upon arrival in New York due to JFK Airport’s strict U.S. Customs and Border Protection (CBP) screening procedures.

Following investigation, Heathrow officials reaffirmed their commitment to reviewing and strengthening security measures, stating that all passengers undergo comprehensive security screenings.

Similarly troubling was a 2022 Frontier Airlines incident, as reported by a media, involving passenger Beverly Ellis-Hebard, who mistakenly boarded a flight from Philadelphia to Jamaica instead of her intended destination, Jacksonville, Florida. Ellis-Hebard lacked a passport, preventing her from legally entering Jamaica upon landing.

This highlighted gaps in adherence to standard TSA and CBP guidelines regarding passenger boarding verification and gate assignments. Frontier Airlines later issued an apology and compensation for the significant inconvenience and distress caused.

Government aviation authorities, including the Federal Aviation Administration (FAA), stress the importance of thorough passenger documentation and security checks, consistently updating protocols in collaboration with airlines to prevent similar incidents.

Such mistakes underscore the critical need for strict adherence to official guidelines to ensure passenger safety and operational integrity.

In response to ongoing security concerns, passengers and crew members alike are encouraged by aviation authorities to familiarize themselves with official TSA, CBP, and FAA guidelines before traveling internationally.
