There's quite a lot of travelling you have to do, and it seems like you have worries and anxiety about each portion of the travelling... it's so not worth it. Please don't worry yourself over this. Try to get excited to see your boyfriend's family and enjoy the holidays. I don't love flying, not because of motion sickness, but because I also have a slight fear of flying. You actually might enjoy it. What you can expect is a really loud noise before take off, which is the engine. That's usually what scares me. You won't get motion sickness unless you've had previous experience in having it (I'm pretty sure). I've travelled on 23 hour flights for years and have done lots of smaller ones, and only one time I had someone have motion sickness on the plane, so I wouldn't worry yourself too much. If you bring a magazine or two, some music on your phone or i-pod and some gum or something to snack on, it may help you. That's the only advice I can give really, just try to enjoy it A lot of my friends LOVE flying so you just might too! Have a great and safe trip. Don't focus on feeling like you will have motion sickness because that will probably make you feel very n*.
