You were able to find out the number of required miles by playing around with the online redemption tool. Now, however, LifeMiles has also made available a very comprehensive award chart for Star Alliance redemptions.
I haven’t had time to fully digest this award chart yet, but they do most definitely have the greatest number of regions especially around the Americas that I have seen.
Have you find any unusually good redemptions/combinations using the LifeMiles? Let me know by leaving a comment below or emailing me at firstname.lastname@example.org.
