so the big in-laws decided we should go to tuscany flying into rome(FCO) so we will all travel together, nonstop YYZ-FCO on the mother-law's expense on AC. 5 of use from YYZ 2 from NYC. they are going to stay longer than my wife and I can stay. So i am trying to figure out how to set myself up to come home on the returning trip, sunday, sept 11, in the forward cabin (whatever carrier necessary to make it happen) because I will have a BIG monday workday. The Biggest dilemma is that one way tix YYZ-FCO is almost as much, or much more than RT (because i was thinking of having her buy the one way and get a oneway award coming home on UA, or CO or AA, anyone that i can). The fares on ITA seem to come up as W fares on AC nonstop out and return on LH through MUC. It seems I am stuck booking a RT ticket, hedging my bets on a return flight that has an upgradable fare? do i just look around for a good trade or sponsored e-upgrade on AC? is W fare upgradable if i can find someone to sponsor/trade? does AC do star alliance upgrades, and if so which miles does one use?
