HOpe I can get an earlier flight....we leave Aus at 12 noon on the day before. As I said, the agent was hoping to book an earlier flight but it wasn't showing. Have gotten 2 different answers from Air Canada, one that I could change flight next that the class of ticket wasn't available. Just hoping we can change as if I can't we won't get to my folks till 10 pm at night.....thanks for your input
