Traveling with a TAA and valve issues

Hello. I have a 4.6 CM ascending aortic aneurysm and a 4.5 CM root aneurysm. Also, one of my aortic leaflets is immobile. Only two are working. And I have “severe regurgitation“. But, I have no symptoms and walk between 3 to 4 miles daily and use lightweights. My daughter lives in Europe and my son lives in Michigan. I live in New York. Has anybody heard of any restrictions on traveling/flying short or long distances. I did an AI search and it said don’t travel anything over four hours. But I want real life information. Can anyone offer what they’ve experienced or heard from their doctors? Thanks.
