I'm thinking of doing a run to EZE via MIA. There's a 45 minute connection between my flight from JFK (which goes onto LIM). What's the chance of missing the connection to AA 909 @ 2230? (AA 2111 JFK-MIA shows 50% chance of punctuality). I'd be put onto AA 911 @ 2345 if I missed that. Actually I hope to so I can save a nigth at EZE.
