I'm planning reward travel from SFO-YYZ in J. I'm looking for some advice on routing and/or equipment strategy. On my outbound leg, I'm probably going to end up routing on a UA or CO transcon (less fees) connecting to a short haul. Any suggestions on routings/equipment to try to pick or avoid? I have not flown transcon F on UA or CO, so I don't know which is better, or if there are planes to avoid (i.e. 737s?). On the return I intend to depart YYZ on AC metal (extra baggage allowance). Is it worth trying to route through LAX or YVR to travel on the 763 because of the suites? Or are the 319/320s that AC flies from YYZ to everywhere in the west just as comfortable for a daytime trip? Thanks in advance!
