They apparently DID fix their site. Out of curiosity, I priced out a r/t ORD-MCO flight just now for a random weekend in October and it showed 1005 miles on the same screen OP posted above. Possibly just a temporary glitch with AA.com.........or a tiny wormhole is temporarily open on your day of travel which shortens the trip by 11 miles but AA still wants your stickers for the "wow" factor.
