Well, we are back and were 7/7 on getting TSA PreCheck on my wife's boarding pass when removing her KTN.

The only problem we had was at JFK in early January. Her new drivers license had been lost in the mail and apparently her temporary NYS paper license was not deemed sufficient ID to use PreCheck at JFK (even though she had the true drivers license in her maiden name as well) so we were directed to the Priority Access line. At least the supervisor (who was already at the PreCheck BP check podium) was willing to walk us to the front of the Priority Access line. According to him the ID needs to have the name match the boarding pass....which was the case unless the temporary drivers license is no longer considered ID. Didn't make much sense to us...Had no issues at PHX coming back a few days later.
