Yes, in 2026, plane tickets are almost entirely digital. The transition to "e-tickets" is effectively 100% complete for commercial aviation. When you book a flight, your "ticket" is a digital record stored in the airline's Computer Reservation System (CRS), identified by a 6-character PNR (Passenger Name Record). What you carry is a boarding pass, which in 2026 is most commonly stored in digital wallets like Apple Wallet or Samsung Wallet. American Airlines recently expanded this integration, allowing real-time updates for gate changes and boarding times directly on your lock screen. While you can still print a paper backup at home or at an airport kiosk, many 2026 "smart airports" are moving toward biometric boarding, where your face or iris scan links directly to your digital ticket record, making even a phone-based QR code unnecessary at the final gate.
