Last week, I some how made a mistake and booked a FLL-SNA via IAH on June 21. It was SUPPOSED to be June 22.

It appears the change fee is 150 ugh. And the Fare difference is 300, GAG.

So in reality I will cancel this and suffer a 150 change fee and get one year to use 50 bucks, which does very little for me.

Since I am out of the 24 hr window, what other alternatives do I have?
