The move is permanent, for now. Meaning that I don't have an "end date" in mind, so I really do want to invest in the loyalty program that offers me the best bang for my money. I'm looking into Asiana and Aegean right now, and both only offer 50% mileage credit for the LH flight (W fare class) that I'm taking in a few days. That only gives me about 2500 miles.

One thing I just noticed - for the airline programs (such as Aegean or Asiana) that require less miles to get gold - they also don't give you as much for the economy tickets that I buy, so the journey to get there is just as long.

In other words, 3/4 of something is still equivalent to 75/100 of something else.
