The Traveler's Prayer, Wayfarer's Prayer or, in Hebrew, "Tefilat HaDerech" is the prayer that petitions the Divine for safe journeys. This is an appropriate prayer for sea, air and even long trips in a car.
The blessing is recited at the outset of each journey and is preferably recited standing. Often it is inscribed on Jewish Jewelry pieces and Hamsa Hands instead of the Blessing for the home, or the Shema Prayer. Keep in mind, all forms of travel, involve a degree of danger. Consequently, we say "Tefilat Haderech".
