Sorry that this experience made you upset. But why complain if we know - just adjust - it's a holiday .

I am at present preparing a trip to Argentina and checking on Flight Aware AR routes like BRC-FTE and USH-AEP are not performing too bad.

Of course I will always allow for a potential 24 hours delay and avoid tight connections.

I think with this attitude and buying flexible and refundable "Club Condor" tickets is the best approach to enjoy traveling without getting upset. Expect the worse and be positively surprised .
