A travel itinerary and a boarding pass are two distinct documents used at different stages of your journey. An itinerary is a comprehensive document—often provided as a "booking confirmation" or "receipt"—that outlines your entire planned trip, including flight numbers, departure/arrival times, confirmation codes (PNR), and often hotel or car rental details. It serves as your "proof of purchase" and is the document you use for visa applications or to verify your schedule. A boarding pass, on the other hand, is the specific document that grants you permission to physically board the aircraft. You only receive a boarding pass after you have checked in (typically within 24 hours of the flight). It contains your specific seat assignment, gate number, and a scannable barcode or QR code. While you might carry your itinerary for your own reference, the boarding pass is the "legal" document required to pass through airport security and to step onto the plane. In 2026, most travelers use digital versions of both, stored in mobile apps or "wallets."
