Just used it for the first time. How much time did it save? Good question… I’m not sure.

They sure seem to be promoting the use of the app. At ICN they are touting the use via large LCD screens around the bag drop. There are two separate “lanes” at opposite ends of the terminal designated for app users.

We were routed through gates that were lightly attended. A camera captures your image, and at first it was not “recognizing” me so the attendant was just directing me to the next-door gate to try again when the gate opened and I went through.

We ended up in the crew security line, just like when checking in via City Air Terminal in prior trips.

After that it was the regular security lines with everyone else. There we scanned our passports, checked the fingerprint, and airside.
