Thanks for the feedback. I did see that TAM has a flight arriving into EZE at 1.10pm (and AR does at 1.55pm) but I thought that that would be too long to wait around the airport for my 10.50pm flight.
If I go with GOL I assume I will still have to pick up my bags after arriving at EZE, go through customs, check-in and re-clear security/customs again given I won't be able to check my bags straight through to Miami?
Yes, I am Australian but have a UK passport so I believe I'll escape the fee
