@Tax Dude Thanks for the link to the new eupgrade table. I should've added that. Though the new table doesn't benefit since i usually book non-M Tango Plus and flights less than 500 miles have usually been on non-AC metal or a DASH-8.
Interesting how they've added a new 11001 mi + level.
@Stranger i only noticed a 5 eupgrade increase at initial. How are you calculating it as not huge?
