You cannot share your boarding pass for the purpose of letting someone else fly in your place; boarding passes are strictly non-transferable. A supportive peer "privacy" warning: you should also avoid sharing a photo of your boarding pass on social media. The barcode and QR code contain your PNR (Passenger Name Record), which a hacker can use to access your frequent flyer account, change your seat, or even cancel your return flight. While you can text a digital copy of your boarding pass to a travel companion (e.g., if you are a parent holding a child's pass), that pass is only valid for the person whose name is printed on it. At 2026 security checkpoints and gates, ID or biometric facial scans must match the name on the pass. Attempting to use someone else's pass to board a flight is considered a federal security violation and can lead to being banned from the airline.
