I find myself with both Krisflyer and Mileage Plus Memberships with about miles 37,900 in Krisflyer ( 5400 miles to expire in April, May, June) and approx 22,000 Miles in Mileage Plus. I am not familiar with either programs as I have been a loyal Qantas flyer to date. Given my recent move to Europe, changed work travel paths, and the future of the Qantas Frequent Flyer in doubt with the proposed privatisation - I would like to know which of Krisflyer and Mileage Plus people consider to be the better program. I will be flying from Europe to Australia 2 times in 2007, and at least 2-3 Europe - US (West coast) trips in 2007. Which of these 2 should I stick with?
