Is It Permissible to Fly During the Three Weeks?

Greetings,

It is permissible to fly between the 17th of Tammuz and Rosh Chodesh Av. However, from Rosh Chodesh Av until after Tisha B'Av, even though it is technically allowed, it is preferable to avoid flying unless it is for a significant need or a mitzvah such as making aliyah to Israel.

Sources: See the book Emes L'Yaakov on Shulchan Aruch (siman 194 note 515) in the name of Rabbi Yisrael Kanievsky zt”l, and in the book Hilchot Shlomo part 1 (chapter 23 note 16) and on the holidays (Nisan-Av chapter 14 paragraph 24) in the name of Rabbi Shlomo Aviner zt”l, and in the book Ashrei HaIsh part 3 (chapter 61 paragraph 3) in the name of Rabbi Yosef Shalom Elyashiv zt”l, and in the collection MiBeit Levi (1999, page 10 note 12) in the name of Rabbi Shmuel Wozner zt”l, and in Responsa V'Darashta U'Vacharta part 5 (part Orach Chaim siman 90).

Best regards,
