Yes today appears to be the first look day!
Fyi it is being extensively covered
here, including the criteria, which is also largely based on an entrance sign that I saw on twitter.
Naturally in true AA fashion, there is now this “flagship” and “non-flagship” itinerary qualifier. Unless AA releases concrete guidance, I’m going to assume that these are the existing rules around when one can access the FLs etc. purely using status on international itineraries (e.g., a trip to the Caribbean gets you AC, not FL, but flying to Europe qualifies as it is long-haul).
