When we traveled late February Vincent with Premium IV said we could fill it out if we wanted, but it wasn’t required. I filled out the form online but never received an email or any other correspondence confirming I had done so. (I did take a screenshot of the page saying “thank you for your submission.”) The AA ticket counter in Knoxville asked for confirmation of the form when I checked my bags (apparently there was “something” in their system prompting her to do so) but she ultimately gave up and took my word for it when I had nothing to show her other than the screenshot. Upon arriving in SXM no one asked about it.
