I hate the fact that I'm on the site on my day off, but I was looking at ways to get from Belfast to Edinburgh in mid-March. Originally I was looking at taking the ferry to Cairnryan and then a bus/train to Edinburgh, but looks like easyjet is cheaper/faster (albeit without the scenery). Only thing that initially stuck out to me was the hand baggage size, as I'll be bringing only a backpack for all my stuff. Anything else I should know about the company?

Should only be an hour flight. Should I anticipate any issues as an American? I would think not, since I'm just travelling between two points in a single county, yeah?
