Hi! Travelling IAH-EWR-OSL tomorrow, Saturday, on CO in Y (my first CO TATL), i am trying to figure out what my options are for upgrading to Business/First on the TATL segment. As all my miles are with SK (I am a SK*G), I have understood that i cannot upgrade for miles (My fare class is to low to use *A upgrades). Currently there is a lot of availability up front (CO 38), the question is how do i get there? Is there any way to buy an upgrade at the gate in EWR or do you know of any other way except from buying up to the higher fare? I have heard that one tactic may be to obtain an SWU, any (legal) means or marketplaces i could get it? Thank you for all advice!
