Just got the usual e-mail about my JFK/EZE flight this evening: "You may now check in for your upcoming trip. (etc.)" So I bop on the check-in buttton, and . . . "Please go to the airport and check in with an agent. We are unable to process your online check-in." Apparently AA doesn't know that AA won't do online check-ins for Argentina flights -- the check-in agent needs to verify the reciprocity fee has been paid before you're allowed aboard. I knew that up-front from previous trips, but I wonder how many pax will get a bit pi**ed off at this bogus message.
