If you have lost your 6-character booking reference (PNR), you can still retrieve your flight details using several alternative methods. Most airline websites and mobile apps feature a "Manage Booking" or "My Trips" section where you can search using your last name and the credit card number used for the purchase, or by using your passport number if it was entered during booking. If you are a member of the airline's frequent flyer program, simply logging into your account will automatically display all upcoming itineraries linked to your name. Another reliable method is to search your email inbox for keywords like "Confirmation," "Itinerary," or "eTicket" from the date you booked. If all digital methods fail, you can call the airline's customer service or visit the airport check-in counter with a valid government-issued photo ID; the agent can locate your reservation by searching your name and flight date. It is a helpful peer tip to take a screenshot of your confirmation screen immediately after booking to avoid this stress in the future.
