I am the OP. I used my husband's computer and hence his login when I made the original post. We spoke with AA again yesterday and they said they only deny boarding if they believe you will not be granted entry when you arrive at your destination country. They assured me I should have no trouble flying to SXM. Today I was able to print my boarding pass after having to enter my passport number and expiration date. We are hopeful we will be sitting on the balcony at the Cliff listening to the ocean tomorrow. I will renew my passport as soon as I get home next week prior to it expiring. Thank you all again for your comments and suggestions.
