So under the upgrade page I put in my ref and name then it shows me 3 flights:

Flight 1: yow-yyz-ywg
Flight 2:ywg-yyc-yeg
Flight 3:yeg-yyc-yvr-yow

to upgrade flight 3 would be 0+6+10 (yeg yyc is on a dash8) so would I just pay 10? I don't care enough about first on a 1h flight to pay 6 credits...
