I am flying ICN-DTW-YYZ Oct 1. They recently changed my flight from ICN-DTW 12:25AM to 10:25AM. I don't want to have to go to the airport so early as I have a lot of things to do before I leave. I will call and ask to change to a later time or next day, however I want to know the probability that I can change to EVEN LATER than that...a few more days or a week or more, at no penalty and fare difference. Is this unheard of? I mean I will ask nicely anyways, but just wanted to see if its happened before.

Thanks.

BTW I got my ticket dirt cheap on a price error, will that affect anything?

I already changed one portion of my trip due to one of their schedule changes because the connection time was too short for me to be comfortable with.

Thanks
