Whether you can go straight to security depends on whether you have bags to check and if you have received a valid boarding pass. If you check in online or via a mobile app and are traveling with carry-on luggage only, you can proceed directly to the security checkpoint using your digital boarding pass. However, if you have checked baggage, you must first visit a "Bag Drop" counter or a self-service kiosk to tag and drop off your suitcases before heading to security. Additionally, for international flights, some airlines require a "document check" even if you have checked in online; in these cases, your digital pass might say "NOT A BOARDING PASS" or require you to stop at a desk for a passport verification. If your boarding pass has a QR code and you have no luggage for the hold, you can bypass the check-in counters entirely and head straight to the gates. It is always wise to double-check the "boarding pass" status on your phone to ensure it doesn't have a "See Agent" notification, which would require a stop at the counter first.
