I e been checking airfare for our return flight. It’s always been 244 just to get home. So yesterday I just bit the bullet and booked. Well I’m the type the even after I book something I like to keep an eye on price. So checking this morning the flight went down almost 50 $. Total. I paid with part GC and the rest cash. Is there anyway I could cancel and rebook and if so what happens to the GC. Thanks all
