When you arrive at the airport, it is normally a good idea to have a printed version of your flight itinerary and boarding card. However, having a physical copy is not always essential, as many airlines now give the opportunity to check-in and obtain boarding passes online via their mobile websites or apps….

While the aviation industry in 2026 is almost entirely digital, you still need access to your itinerary, though not necessarily in paper form. For most domestic travel, your digital boarding pass in an Apple or Google Wallet is sufficient. However, for international travel, many countries and airlines now strictly enforce "Proof of Onward Travel" rules. Immigration officers or check-in agents may ask to see a confirmed itinerary showing your flight out of the country before allowing you to board or enter. In 2026, it is highly recommended to keep an offline PDF copy or a high-resolution screenshot of your full itinerary (including flight numbers and booking references) on your phone. This ensures you can provide proof even if the airport Wi-Fi is weak or your airline app fails to load. For certain visa-heavy destinations, a physical printout is still the "safest" backup to avoid delays at manual document verification counters where digital screens are sometimes not accepted.
