IM a spring chicken in present company with only about 25-30,000 k's under my belt most years, however, with the exception of my personal trips every few years - it's all in Y and all domestic (never been in F or J, spent a bit of time in Y+ recently though...). For me, I am not sick of flying at all and I don't think I ever will. I love transit and every part of it. We are about to leave on a 28 HR journey, for a holiday, and although it is all in Y, I am looking forward to it as much as any other part of the holiday. What I am sick of is time away from the family, even if it is for a few days, it seems like you miss out on soooooo much. If I could have them at the destination, I'd be a happy camper. I happen to love being in transit by myself for the whole "me" time!
