A string of vanishing acts by Pakistani air hostesses upon arrival in Canada has raised concerns about Pakistan International Airlines (PIA). The latest case involves an air hostess named Maryam Raza who left a note expressing gratitude to PIA in a Toronto hotel room before disappearing. This incident marks the second disappearance of a PIA flight attendant in 2024 alone, with experts attributing the trend to low salaries and uncertain prospects at the airline.
