I am looking to go away for about 4 or 5 days - use up an expiring credit on Air Canada. Obviously I want to gather the maximum number of miles at the same time.

Of the choice of HKG, DEL or EZE where would you go? I have never been to any of them and all would cost about the same (with EZE being slightly less).

Thoughts?

Merci
