So the thread on how much business class alleviates jet lag made me wonder... over the last few years, I've been getting motion sickness on flights. It's really miserable, and I''ve tried meds and acupuncture bands and all that with no result.

So for my next trip, I'm saving up to fly business class. It's expensive, though, because I live down south of Africa, and generally travel to Europe. How much is it likely to help? Obviously the motion of the plane and the drone of the engines is the same, but it would feel a lot less claustrophobic (due to the motion sickness, I've also started getting edgy and feeling a bit trapped in economy). Would lie flat seats help, changing the angle of your head?

Or am I just paying a lot of money for more room for my barf bag?
