Just was looking at some tickets to Mexico and the Caribbean for this winter and noticed many dates with Economy Awards coming out to 55k miles in Mid Level. I remember these always being 50k miles at mid level. Is it just me or did something recently change?? Europe looks goofy to me too. I thought it was 60k/90k/125k, no? Here is the link to the award chart:
