Amex membership rewards and airlines
I am only familiar with transferring these to Emirates Skywards miles (one point = 880 sky-yards, hardly a bargain) and Avios. I have quite a lot of Amex points, they don't expire so I have saved them up rather than transferring them to a 'loyalty' scheme, Any suggestions as to where I will get the best flights per point? Airlines seem to differ wildly on where you can actually go for a given 1,000 points, the expression 'mile' seems to be almost meaningless.
I wouldn't mind going back to Medellin with Avianca, which I understand is an airline that lets you fly about the furthest for an Amex point, but I'd really like advice from frequent flyers.
