I had started a new thread on the same topic unaware that this topic was already being discussed here.

My post from that thread is as follows:


My wife and I are going to Dallas to be with family over thanksgiving. I am booked to fly out this Wed (the 26th), while she is flying out tomorrow (tuesday). The reason to book my flight for the later date was a meeting here in NY tomorrow. The meeting is now cancelled and am contamplating getting out on the same flight as my wife. We are both on K fares.
What is the policy on standing by for a flight a day in advance? I do not plan to make new reservations, just go and request the agent at check-in. I don't have a problem paying the $100 cange fees, but to pay the difference in fare would be a bit much (its over a 1,000 bucks now). The question then is that will I be able to get on a flight a day prior with just the change fees or will I need to pay the fare difference as well. Again, I don't plan to change my reservation in advance but just try my luck at the airport.
Thanks much in advance
