Hi Amanda,
What company are you going with? Hopefully you flight isn’t too long as it’s not recommended that you fly for a minimum of 6 weeks- but I’m sure you know that.
It’s up to you obviously but I really wouldn’t risk going swimming at all, whether it’s in the sea or a pool. Your incisions might not sealed fully and will be really prone to infection. Also, you’re supposed to wear a post-op bra pretty much 24/7 for 6 weeks so you won’t be able to swim with that on anyway.
If you’re just planning on going in the water up to your waist then that might be alright but again I personally wouldn’t.
Sorry if I seem harsh, just doesn’t seem worth you getting infections or anything after you’ve paid all that money to get them done 🙂 xx
