To check if your flight is confirmed, the most reliable method is to use the Manage Booking tool on the airline's official website or mobile app. You will need your Booking Reference (also known as a PNR or Record Locator), which is a six-character alphanumeric code, along with your last name. Once logged in, your flight status should explicitly say "Confirmed" or "Ticketed." If it says "Pending" or "On Hold," your seat may not be fully secured, often due to a payment processing delay. Another way to verify is to check your email for an e-ticket receipt; a confirmation email is not always enough, as the actual e-ticket number (a 13-digit code starting with the airline's specific three-digit identifier) is the legal proof that a seat has been paid for and reserved in your name. You can also use third-party tools like CheckMyTrip or ViewTrip by entering your PNR. If you booked through a travel agent or a third-party site like Expedia, it is highly recommended to double-check directly with the airline, as there can occasionally be communication gaps between the agency's system and the airline's manifest. Finally, you can call the airline's customer service, though using the app is significantly faster in 2026.
