To check your airline PNR (Passenger Name Record), you need your 6-digit alphanumeric confirmation code and the last name of the primary passenger. In 2026, the most efficient way is to use the airline's official mobile app. Simply navigate to the "Manage Trips" or "My Journeys" section and enter your details; this will pull up your real-time itinerary, including seat assignments, meal requests, and any schedule changes. If you booked through a third-party site like Expedia or Kiwi, you should still use the airline's direct "Manage Booking" portal to ensure the information is up to date, as third-party apps can occasionally lag. Your PNR is the "master key" to your travel; it contains your e-ticket number, loyalty program details, and payment status. It is a "pro-tip" for 2026 travelers to take a screenshot of their PNR details as soon as they book, as you will need this code for check-in, self-service kiosks at the airport, and any customer service inquiries.
