May it be Your will, Lord my God, to lead me on the way of peace and guide and direct my steps in peace, so that You will bring me happily to my destination, safe and sound. Save me from danger on the way. Give me good grace, kindness and favor in both Your eyes and in the eyes of all whom I may meet. Hear this my prayer, for you are a God who hears to the heart's supplication and communion. Blessed are You, Lord our God, who hears prayer.
~~Tefilat HaDerekh, the Jewish prayer for travelers; according to some practices, recited just before the plane takes off, to extend the hope for safety to every plane in the sky
Be mindful, O Lord, of those who travel by land, by sea, and by air; of the old and young, the sick, the suffering, the sorrowing, the afflicted, the captives, the needy and the poor; and upon them all send forth Thy mercies, for Thou art the Giver of all good things.
~~Orthodox Christian liturgy
O Almighty and merciful God, who has commissioned your angels to guide and protect us, may they be our companions from our setting out until our return. Clothe us with their invisible protection; keep from us all danger of collision, of fire, of explosion, of falling; and finally,having preserved us from all evil, and especially from sin, guide us to our heavenly home. Through Jesus Christ, our Lord. Amen.
~~Roman Catholic Prayer for Travelers
In the name of Allah! I have placed faith in Allah and I have put full trust in Allah. It is as Allah wills! There is no strength and no power save with Allah.
O Allah! Protect me and protect what is with me, and deliver me to my destination. By Allah I commence my journey; by Allah I seek to accomplish the purpose of my journey; and by Muhammad (s.a.w.) I have set out. O Allah, make me overcome all; and make easy for me all difficulties; and give me more of goodness than I hope for; and keep away all evil of which I am apprehensive for my health, O the most Merciful.
