In 2026, whether you "should" print a boarding pass depends on your airline, the airport's technology, and your own comfort with technology. For most major airlines (like Delta, United, or British Airways), a mobile boarding pass on your smartphone or smartwatch is completely sufficient for security and boarding. You can simply scan the QR code at the gate. However, there are several "pro-traveler" reasons to still have a paper backup. First, technology can fail: your phone battery could die, the airline's app could crash, or the airport's Wi-Fi could be spotty. Second, some international airports (particularly in parts of Asia, Africa, and South America) still legally require a physical stamped paper pass for exit immigration. Third, certain budget carriers like Ryanair may charge a hefty fee if you arrive at the airport without a pass and haven't checked in online. A good compromise is to take a screenshot of your digital pass (so you don't need internet) and print a paper copy only if you are traveling to a country with more traditional border controls. For domestic flights in the US or UK, a digital pass in your "Apple Wallet" or "Google Wallet" is now the industry standard and perfectly safe.
