Ever since removing their award charts from public view, Delta has seemed to go out of their way to find more and more ways to stick it to their SkyMiles members like imposing basic economy restrictions on the least expensive awards and eliminating high value upgrade awards.
Now they have a new trick to charge you more miles — and since they don’t tell you how their pricing works you might never even know it and wind up spending more miles than you have to for the same itinerary! Delta now charges more than 50% the roundtrip cost of an award for many international redemptions.
