This is my first time flying on my own and when I booked my flight online I stupidly added a checked bag without even thinking. However I've realized I can easily fit everything I need in my cabin bag and won't need a checked bag at all. So I have two questions:


1) Any chance I'll be able to cancel the checked in bag and get a refund? (ok, even I know this is about as likely as hell freezing over)

2) Should I just ignore the bag-drop desk and just go through to board when I'm at the airport? Or would it be best to go explain that I won't be needing a checked in bag?
