I also suggested another option-
If you have enough trips to get 40,000 kms(25,000 miles), you can get Premium status at Lanchile, which comes with two upgrade certificates valid on the next class of service and can only be redeemed at check-in.* Upg. are valid only with LanChile, LanPeru and you'll also need 4 segments w/LA to obtain elite status
Another advantage is if you're not planning to use the miles w/Lanchile, you can always transfer them to HHonors.
10,000 LanPass kms= 10,000 HHonors
Another option I was looking at was through AS.. But I don't use that carrier, so for me LanChile is my top choice.
