Final answer:
To check a flight booking, access the airline's official website and enter your booking reference in the 'Manage Booking' section to review your itinerary. ACS provides flight loading details, while PBT refers to the ticketed passenger's booking details.
Step-by-step explanation:
To check the booking of a flight, you would typically need your booking reference or confirmation number, which is provided to you at the time of booking. Regardless of whether the booking system is the Airline Reservation System (ACS) or Passenger Name Record (PBR), the process is similar. Here is a general idea on the steps you might have to follow:
- Visit the airline's official website.
- Navigate to the 'Manage Booking' or 'My Trips' section.
- Enter your booking reference and last name in the respective fields.
- Review your flight details and itinerary.
If you are using an ACS, you might access more details about the flight loading and status, whereas PBT often refers to the ticketed Passenger's personal details and booking specifics.
For more detailed information, it is usually recommended to consult with the specific airline's customer service or help desk.
