Notice that my flight from YVR to YYZ has had a time change. It is now leavling one half hour later, arriving in YYZ one hour prior to my AC International connection. I had previously booked this giving myself one hour thirty minutes between flights. One hour is a valid connection time according to AC. However with the construction at YYZ and flights now arriving late, this particular flight arrive 1 hr 20 minutes late last night, I am thinking of going out to YVR earlier and trying to stand by for an earlier YYZ flight, am *G with UA, which probably does not hold too much water with AC. The question, has anyone had luck flying standby on AC without having to pay a change fee? Are the agents understanding, helpful, customer oriented or is the same old AC of yester year?
