In 2026, you generally do not need to visit the check-in desk if you have checked in online via the airline's app and are traveling with carry-on luggage only. You can simply head directly to security with your mobile boarding pass. If you have checked luggage, many airports now feature "Self-Service Bag Drops" where you scan your boarding pass, print your own tag, and place the bag on the belt yourself, bypassing the desk entirely. You only must go to the desk if: 1. You are traveling on an international route that requires a physical passport/visa verification that couldn't be done via the app; 2. You are checking "special" items like strollers or sports equipment; or 3. You are traveling on a "Basic Economy" fare with an airline (like United or Ryanair) that requires an agent to verify your bag size before issuing a pass. If the app says "This is your boarding pass," you are usually good to go!
