The EZE flight was about 2 weeks ago, and the 1K GA at SAN waffled about a second, and then after conversing with another GA agreed that there wouldn't be any charge for the bike on an international itinerary. I didn't get the sense that this was a premier benefit, but perhaps it is.

You can call res and they will tell you one way or the other if you want to know before you leave. Mike is correct in assuming the worst and hoping for the best. This works out in almost all situations!
