Hi love,
Just double check with your nurse. It’s not a case of whether you feel up to it, it’s a health reason relating to DVT. If you’ve flown long haul (12 to 15 hrs) and looked at your legs at the other side you’ll have surely noticed quite a swelling (even with the ‘magic’ socks on!) so imagine that happening to newly operated on bodies! urgh!
Just go with what your nurse says. I’m sure it’s worked out with an extra margin of safety in anyway, like: minimum recommended safety time + a little extra safety time = recommended time before flying long haul! ha ha check out my maths!
