What does the code PSPT stand for in relation to passenger travel?

The code PSPT stands for "Passport Information." In the context of passenger travel, it relates to the documentation required for international air travel, where a passport is essential for identity verification and border control. Airlines and travel authorities often require passengers to provide their passport details during the booking process or prior to travel to ensure compliance with immigration laws.

Understanding passport information is crucial for a smooth travel experience, as it allows airlines to verify that travelers have the necessary documentation to enter their destination country. This prevents boarding issues caused by inadequate paperwork, thereby facilitating efficient processing at airports.

While the other options present plausible interpretations, they do not encompass the widely recognized terminology associated with PSPT in passenger travel contexts.
