I’m flying to Asia soon. Am I machuev to bencht Gomel when I return?
The common custom is to bench Gomel after a flight. This certainly applies to a flight from Asia.
Although some have claimed that the berachah does not apply to flights, which are not included in the enactment of Ha-Gomel, the prevalent custom is to recite the blessing.
Sources: Iggros Moshe, Tzitz Eliezer, and Yecheveh Daas write that Ha-Gomel is recited after a flight, because a flight is also a departure from the ordinary order in the world, and involves some danger, like sailing over the sea. This opinion is also stated in the name of Chazon Ish. Betzel Hachochmah, and some other authorities, write that the blessing should not be recited.
