I got ruffly 150K CO miles and would like to book a trip to TUN....when attempting to look for the first segment, I am finding availability out ..but is this availability jus showing that theres 'availability' in that class? or does it mean I can use my miles in the saverpass to get it?
(hope im making sense)..
