Now that is a good thing to recall. AA has monkeyed around with schedules in a major way over the last year--I've had many flight times changed (although not dramatically). I think I will go for the later AEP-USH flight just to be safe. Who knows, if I arrive at AEP wildly early, maybe LAN will let me jump on the earlier flight. I'm traveling on DL miles though, so I will keep my expectations very low.

What should I expect to pay for the taxi between the two airports? Do I need to hit an ATM for pesos, or will USD be accepted? (Sorry for the dumb question on currency but I haven't been to Argentina since 1997 and I don't know what they're doing as far as money these days.)
