Hi there, i have a question regarding the use of SWU
I´m flying EZE-MIA-YYZ and i´ve asked for upgrades round trip using SWU; however I´m not sure if they are applying 1 SWU per "section" or just one for each travel. I mean; will they use 4 of my upgrades to do this? or will they use just 2?
Because I think Its not worthy use one upgrade like this one for a 3.5hs travel like MIA-YYZ... and i though it was only 2 for the whole round trip.
thank you!
