You can go straight to security only if you meet two specific conditions: you have already checked in for your flight and you do not have any luggage that needs to be checked at a ticket counter. In 2026, most travelers utilize mobile check-in via an airline app 24 hours before departure, which provides a digital boarding pass with a QR code. If you are traveling with only a carry-on bag and have this digital pass on your phone (or a printed copy from home), you can bypass the check-in kiosks and the long lines at the "Bag Drop" or ticket counters entirely. You simply walk directly to the TSA or security entrance, present your boarding pass and a valid government-issued ID, and begin the screening process. However, if you are traveling internationally, some airlines may still require you to visit a desk for a manual "document check" to verify your visa or passport before the app will issue a scannable boarding pass. If the app gives you a "this is not a boarding pass" message, you must visit a kiosk or counter before heading to the security checkpoint.
