Definitely not obvious that the Priority Security Perk is not the same as TSA PreCheck.

In my case leaving BOS there is a Priority Security line where this can be used.

Leaving JAX there is only TSA PreCheck but no Priority Security.

Confusingly in the past I have had TSA PreCheck on my boarding pass and never paid for it.

Checking today (Dec 28, 2023) if you want TSA PreCheck you need to submit a form, pay $78, and requires a security interview.

Good to know ill have to check each airport for Priority Security vs TSA PreCheck.

Hey JetBlue, if we are Mosaic you should sponsor our TSA PreCheck!
