I recently received an email from American regarding my flight MIA - SXM on November 2. There was a link within the email regarding required documentation. When I followed the link, it took me to a webside, Sherpa, I think, that showed the EHAS form was still a requirement. I sent them an email with a link to the updated guidelines. They wrote back thanking me for the information and removed the EHAS requirement from their site. Whether American knows this is another question.
