So in two weeks I leave for a semester abroad and I'm excited but I have some first time travel questions.

The main one is really this: I'll be doing some weekend travel in Europe so I want to take a backpack. Should I just check one piece of luggage and have my carry-on be a backpack or try to roll up a backpack and stick it in my checked bag? I have a carry-on luggage case that I was planning on using instead of a backpack.

If anyone has any advice for surviving a ten hour flight that is mostly at night (which is going to be my first one ever), I would love to hear it!
