Question:
A relative flew from USA to London on shabbos. Can we speak to them after shabbos in London from the same tome zone.
Answer:
It is permitted. The reason is that although the person did melacha on shabbos, but it isn’t as if they made something for you that you would not be allowed to benefit from it. Additionally it doesn’t look like the person flew for you, therefore it would be permitted.
Best Wishes
