There might be minor differences between airlines but if you have checked in online and printed your boarding pass then you just need to go to the bag drop desk (most airlines have separate bag drop desks) to hand over your bags. There is a place called bag drop which basically looks the same as the old checkin desks.

If you have already checked in online and received your digital boarding pass, your high-fidelity airport procedure depends on whether you have luggage to check. If you are traveling with carry-on only, you can head straight to the security checkpoint upon arrival, bypassing the check-in counters entirely. If you have checked baggage, you must look for the "Bag Drop" kiosks or counters. In 2026, many major airports utilize "Self-Service Bag Drop" machines where you scan your boarding pass, print your own tag, and place the bag on the belt yourself. Once your bags are handled, proceed through security as normal. It is a high-fidelity best practice to still arrive at least two hours early, as security queues and terminal distances can be unpredictable, especially during peak 2026 travel windows.
