...there have actually been no major changes to the comparison tables.
That is incorrect. Most recently, award and/or upgrade information for FI, IB,and KE as been updated or added to ExpertFlyer since
Lux made his comparison chart.
In addition, AwardNexus, which has full award availability for all major alliance airlines as well, is not included in the charts at all. Certainly a major change for those wanting to know about
all options available when evaluating the best solution.
