The 7th of Pesach this year was celebrated in Israel on Friday, and overseas on Friday and Saturday. This caused a discrepancy in Parsha reading between overseas and Israel, since outside Israel the reading for Pesach took the place of the reading for shabas. If someone flies from Israel abroad (and vice versa) and will be there on Sabbath, he hears a Parsha he had heard before (or in the second case misses a Parsha).
The discrepancy this year persists between 14th April and 19th May (Leminyanam).
What is the solution for such a person in Halacha?
Is The Halacha recommended to not enter to this situations ?
I read along time ago in Yalkut Yosef that Harav Ovadia had similar situation and when he comes back to Israel, he recived first Aliya to the Torah, and they read for him the previous Parasha and the First Aliya for the current Parasha, but this could be an option only for Harav Ovadia (or another respectable Rabbi) that the audience accorded respect.
