Thanks for the replies
Thanks for the advice on time. My friend who lives in La Plata. Advised me on the long waits at the airport. His thinking is it will be a bit better in the morning since not many intl flights go out then.
I tried calling customer care again but after being on hold for 20. (With a 5-10 quoted) Skype cut out. I am going to try for a hotel and then miles/voucher.
The time of the flight is less than ideal for transport and jet lag.
Got through and they told me I had to do that at the airport and then the call dropped..... Guess I'll try once I get back to the EE.UU
Ciao,
Pablo
