thanks - I know I can do that, and it is actually a little cheaper than flying DL, but I am concerned about possible delays on the first flight making me lose my connection. In that case, it is hard to get rebooked on another flight or -on the way back- i may not get another flight to NYC on CO until the following day.

If anyone, looking at past history, could shed light on how soon we'll know whether CO will get the rights to fly to EZE, that would be terrific.

Thanks
A.
