If you have already checked in online in 2026, you generally do not need to visit the check-in counter if you are traveling with carry-on luggage only. You can proceed directly to security using the digital boarding pass on your phone. However, there are three major exceptions. First, if you have checked bags, you must go to a "Bag Drop" kiosk or counter to tag and deposit your luggage. Second, for many international flights, the airline is legally required to perform a physical document check (passport and visa) before you can board, which often must happen at the counter even if you have a mobile pass. Third, some 2026 "low-cost" carriers or specific airports (like those using the DigiYatra system in India or biometric gates in the EU) may require you to "validate" your digital ID at a kiosk upon arrival. Always check your app’s specific instructions, as "Web Check-In" is only the first step of the 2026 departure flow.
