Flying out tomorrow. My wife USUALLY gets pre-check along with me on her boarding pass, but did not this time. I am PLAT and entitled to use 1st class line at security. But, I'm PLAT, so traveling in coach of course (had my 1 yearly upgrade back in Nov).

Due to the pain of dealing with my liquids and shoes, I'd like to go thru pre-check with the carryon and send her thru 1st class line. Her boarding pass says 'Priority' on it while mine says 'Priority / Platinum'. Will she be allowed to use the 1st class non-precheck line alone, or do I need to be with her (and break out the ziploc bags)?

Want to get this sorted today rather than 5:00 am tomorrow at Sky Harbor.
