The aviation industry is no stranger to unexpected incidents, but a recent United Airlines flight from Los Angeles to Shanghai left passengers in disbelief when it was forced to turn back mid-flight. The reason? One of the Pilots Forgets to Bring Passport. This seemingly minor oversight resulted in delays, frustration, and financial costs, bringing attention to the importance of airline protocol and discipline.
The Unexpected Turnaround: What Happened Mid-Air?
United Airlines Flight UA 198 took off from Los Angeles International Airport (LAX) on March 22, 2024, at approximately 2 p.m. with 257 passengers and 13 crew members aboard. The aircraft, a Boeing 787, was bound for Shanghai, China, on what was expected to be a routine international flight.
However, about two hours into the journey, a surprising realization forced the plane to alter its course. One of the flight’s pilots discovered that they had forgotten their passport, making it impossible for them to enter China upon arrival.
Faced with this predicament, the airline made the decision to turn the flight around and reroute it to San Francisco International Airport (SFO), where a new crew could be arranged. According to FlightAware, a flight tracking website, the plane landed back in San Francisco at around 5 p.m. local time.
The unanticipated return meant passengers were stranded for several hours before an alternative crew could be arranged to take them to their destination. Eventually, the replacement flight departed at approximately 9 p.m., arriving in Shanghai six hours later than originally scheduled.

Passengers were compensated for the inconvenience with meal vouchers, and United Airlines assured them that their cases would be reviewed for additional compensation. However, the delay had a domino effect, not only affecting those onboard but also disrupting the airline’s return flight operations and frustrating many passengers.
Passenger Reactions: A Mix of Frustration and Understanding
For those aboard Flight UA 198, the unexpected delay was met with mixed emotions. Chinese passenger Yang Shuhan shared her experience, noting that the pilot had announced the situation with a tone of clear frustration.
According to Yang, the pilot admitted over the intercom, “I forgot my passport,” an admission that left passengers stunned. Many found it difficult to believe that such an oversight could happen in an industry known for its rigorous pre-flight checks.
Upon landing in San Francisco, Yang was given two meal vouchers totaling $30, which she used at a Japanese restaurant in the airport. While she appreciated the airline’s transparency, she admitted that the delay left her exhausted, as she still had a long drive ahead after reaching Shanghai.

Her exhaustion and frustration were echoed by many others, with numerous passengers expressing their outrage on RedNote, a Chinese social media platform akin to Instagram. A viral post by another passenger questioning how such an error could happen garnered over 10,000 likes, illustrating the widespread disappointment among travelers.
The repercussions of this error extended beyond just Flight UA 198. The return flight, UA 199 from Shanghai to Los Angeles, was also delayed by approximately six hours due to the late arrival of the inbound aircraft.
A business traveler from Shanghai, who preferred to remain anonymous, expressed their frustration at having to rearrange their connecting flights and reschedule important meetings upon arrival in Los Angeles. “It’s really inconvenient,” they said, emphasizing the significant impact even a minor oversight could have on passengers’ plans.
Industry Experts Weigh In: An Embarrassing Mistake for United Airlines
The incident has drawn sharp criticism from aviation industry experts, with many pointing out that such an oversight is highly unprofessional for a major airline like United. Shukor Yusof, founder of the Singapore-based aviation advisory firm Endau Analytics, described the situation as “embarrassing” and “unacceptable” for a globally recognized airline. He noted that the incident demonstrates a lack of discipline, which could have serious repercussions for United’s reputation and finances.
From a financial perspective, the blunder was costly. Beyond the logistical expenses of rerouting the plane, there were additional costs associated with jet fuel dumping, crew replacement, meal vouchers, and passenger compensation. Such missteps can tarnish an airline’s reputation, particularly when coupled with other controversies.

United Airlines has faced multiple public relations challenges in recent months. Just last week, an Orthodox Jewish passenger filed a lawsuit against the airline, alleging that a United pilot forcibly removed him from a lavatory while he was experiencing severe constipation. The lawsuit claims that the passenger’s privacy was violated, further denting United’s reputation.
In another recent controversy, a New Jersey mother criticized United for asking her to remove her medically complex son’s breathing tube before takeoff. Her viral TikTok post, which has been viewed over 1.3 million times, brought further scrutiny to the airline’s policies and customer service practices.
While the passport incident does not pose safety concerns like mechanical failures or in-flight emergencies, it does raise questions about airline procedures and pre-flight checks. How did a pilot manage to board an international flight without a passport? Many argue that such a crucial document should be checked as part of standard pre-flight protocols.
United Airlines’ competitors will likely use this incident to their advantage, emphasizing their own stringent protocols to avoid similar errors. The airline industry is incredibly competitive, and maintaining passenger trust is essential.
Travelers, particularly those on international routes, expect professionalism and attention to detail from airlines, and even small lapses can result in reputational damage.
A Lesson in Discipline and Protocol
The bizarre incident involving Flight UA 198 serves as a stark reminder of the importance of discipline and protocol in the aviation industry. While human errors are inevitable, airlines must have stringent safeguards in place to prevent such incidents from occurring.

A pilot forgetting their passport may seem like a simple mistake, but the ramifications extend far beyond a minor inconvenience. Hundreds of passengers faced delays, financial losses, and disruptions to their plans, while United Airlines suffered reputational and financial setbacks.
Moving forward, it remains to be seen how United Airlines will address this issue internally. Will they tighten their pre-flight checks to ensure pilots have their necessary documents before departure?
Will they introduce new policies to prevent such oversights in the future? The airline’s response will be critical in rebuilding trust among passengers and reinforcing confidence in its operational discipline.
For now, this incident stands as one of the more unusual disruptions in recent aviation history—a stark example of how a seemingly trivial oversight can lead to widespread inconvenience and financial losses.
Passengers will hope that airlines take this as a wake-up call to enforce stricter compliance with pre-flight protocols, ensuring that no similar mishaps occur in the future.
