I'm pleased to learn that Aer LIngus now participates in TSA Pre-check--but where and how to add the KTN number to the booking? Does not seem to be an option and their website says nothing....

I would call customer service.

I know for Delta & United, you add your KTN in your passenger profile, not to each booking,
So go into your account on Aer Lingus and look and see if there is a place to add it there.

You probably don’t want to leave it this late, but when we just traveled to/from Ireland on American (which I think codeshares with Aer Lingus), there was an option to add our KTNs as we were checking in at the self-service kiosk. Your boarding pass should be updated to reflect it at that point.

In the future you can add the number(s) when you make the reservation. For now you can call and have customer service add it to the passenger details, or as a previous poster said you can add it at check in, at the airport.
