goodo, it's fine that you want to fly a lot, but I am just cautioning you of a few potential problems. First, some of these countries are not going to understand what a mileage run is, and you run a severe risk of getting hassled. I stood and watched hk-umich get nailed one time at the gate in Santiago, and it wasn't fun. I have had my fair share of agents hassling me, including the good ol' USA, pre-9/11. You are talking about going to places that are not pinnacles of stability and lawfulness, and doing something that looks awfully fishy to someone who doesn't get paid enough to give a hoot about your mileage account. Second, there is far more to planning one of these things than just deciding what is furthest away. For example, Caracas has had a schedule for a long time that keeps people from doing turnarounds because the return flight leaves before the arrival. Same with Easter Island. Or in the case of Sri Lanka, you have to stopover in Bangkok, so a 5 hr flight quickly becomes 7 or 8. Customs aside, a non-stop Delhi flight becomes potentially more attractive. Okay, here is another. Visa issues. Last time I looked, you needed to secure a Kenyan visa ahead of time, even for a transit. There is a $30 reciprocity fee in Chile for you if you choose to stop. There is also a $20 departure tax, which often is not put on the ticket. Some places will force you to pass customs when you arrive, which means you will have to pay fees when you leave.
