We were thinking about the train but it's more than driving. We're now thinking about flying. We have ever taken a plane for anything. With that said here's my questions (so far): 1) where to look to get the cheap tickets, what if we change our mind could we get refunds? 2) what's some of the rules with liquids? what can I take and not take? I'm so new I don't know what questions to ask, I need HELP!
