How is it possible to lain the same haftora two weeks in a row?
Probably not the answer you are looking for, but if I was in E"Y where they were one week ahead in torah reading and then came back to Chutz La'aretz.
This year for example, if You were in Israel for the Shabbos of June 6th, and returned to the US for the Shabbos of June 13th, and had maftir on each shabbos you would have lained the same haftorah (Behaloscha) two weeks in a row.
