Has anyone recently taken this route on Delta? We are traveling on Feb 19th and transiting through AMS to Tanzania.

My questions are:
1. Do all ATL to AMS route allow the rapid antigen test at Gate E14 or just the "Covid-Tested" designated segments?
2. Based on the Amsterdam requirements do I take the PCR test 72 hours prior to boarding or 5 days prior (I'm transiting in AMS)?

Thanks for any help!
