Just got an email about a Net SAAver deal, JFK/LGA-EZE for $477 + taxes and fees eachway.
Fares must be ticketed no later than 11:59 p.m. (CT) Sunday,
June 19, 2011, for flights departing anytime Tuesday, June 21, 2011, through Friday,
June 24, 2011, with a return the following Monday through Wednesday.
Only bad thing is that travel can only last for a week. For such a long flight it would be nice to have it stretched to 2 weeks. Anyway, not sure who else is based out of NYC that flies to EZE, but this is a great deal. The best price I have ever seen for this flight in the past was $800 each way before taxes and fees.
