For instance, if you aren't checking a bag, you can skip the lines at the check-in counter and proceed directly to airport security with your carry-on bag and an electronic ticket. A carry-on bag is just one more item that security personnel may need to search.

In 2026, you can go straight to security with hand luggage only if you have a digital or self-printed boarding pass and are flying on a domestic route. For domestic travel in the U.S., UK, or EU, most airlines allow you to check in via their app 24 hours in advance; once you have your mobile QR code, you can bypass the check-in counters entirely. However, for international flights, the rules are stricter. Even if you only have a carry-on, many 2026 airlines require you to visit a "Document Check" desk or a self-service kiosk so they can physically or digitally verify your passport and visa requirements before you enter the secure zone. In some countries, like India, airport security will not let you pass without a physical stamp on your boarding pass, meaning a trip to the counter is mandatory regardless of your luggage status. Always check your app—if it says "Boarding Pass Not Issued," you must visit the desk.
