Have you ever bought plane tickets in advance only to realize you need tickets on a different date? what do you do with the tickets that you already bought? do you just take the loss, or try to resell them

YES!

I DON'T KNOW WHAT I AM SUPPOSED TO DO!

the airlines will usually change that for you, no charge. as long as your not cancelling your flight or anything. call them and see what they can do for you.

Usually you can always change them? Even if you have to pay to change them... Call the airline or whoever you bought the ticket with and figure out what they can offer you.

I don't think you can actually resell them to someone else though, because it was bought in the passengers name...?

The airlines change the date for you =] I think you get charged a little though...

I went to Kansas City last year and was bored and came home early. Delta charged me $75 to change it..... boo! But it might be because I was half way through my trip... Idk but yeah, they charged me.

It depends on the airline. I've had that problem before, and I had to pay a fee to change them, plus the difference in fare.

I changed mine once, and I had to pay like $60, but I think it was partly because I changed it to a date that was like two days after I called to change! Just call yo!

depending on what kind of fare you bought they can change them, no charge. i'm booking a flight soon, but i'm booking a really cheap one which means i can't do certain things. like change or cancel the tickets.
