Now I study ESL in Canada, my original flight schedule back to Taiwan is July 5th. Yesterday I got the news that my grandmother died, so I have to go back to Taiwan next week, and then back Canada. I have checked the flight ticket, it's cheaper in Taiwan than buy it in Canada. Now I have two options: 1.Buy the round-trip ticket in Canada directly. 2.Change my original flight schedule to June, and buy another round-trip in Taiwan. But July is high season, if I do it, I am afraid the flight is full and I can't book the original schedule again, and complex.... If any one experienced can advise me, which one is better, or any more suggestion. Thanks a lot!!
