The Messenger of Allah (ﷺ), used to recite this du'a when he was on a journey:
اَللَّهُمَّ أَنْتَ الصَّاحِبُ فِي السَّفَرِ وَالْخَلِيفَةُ فِي الْأَهْلِ اَللَّهُمَّ إِنِّي أَعُوْذُ بِكَ مِنْ وَعْثَاءِ السَّفَرِ وَكَآبَةِ الْمُنْقَلَبِ وَسُوءِ الْمَنْظَرِ فِي الْأَهْلِ وَالْمَالِ اَللَّهُمَّ اطْوِ لَنَا الْأَرْضَ وَهَوِّنْ عَلَيْنَا السَّفَرَ
Pronunciation
Allaahumma 'Antas-saahibu fis-safari wal-khaleefatu fil-'ahli, Allaahumma 'innee 'a'oodhu bika min wa'thaa'is-safari, wa kaabatil munqalabi wa su'il manzari fil-ahli wal maali, Allaahummatwi lanal-arda wa hawwin alainas-safara
Meaning
O Allah, You are the Companion in the journey, and the One Who looks after the family; O Allah, I seek refuge in Thee from the difficulty of travelling, finding harm when I return, and unhappiness in what I see coming to my family and property. O Allah, make the length of his journey short for us, and the journey easy for us.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، حَدَّثَنَا مُحَمَّدُ بْنُ عَجْلاَنَ، حَدَّثَنِي سَعِيدٌ الْمَقْبُرِيُّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا سَافَرَ قَالَ " اللَّهُمَّ أَنْتَ الصَّاحِبُ فِي السَّفَرِ وَالْخَلِيفَةُ فِي الأَهْلِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ وَعْثَاءِ السَّفَرِ وَكَآبَةِ الْمُنْقَلَبِ وَسُوءِ الْمَنْظَرِ فِي الأَهْلِ وَالْمَالِ اللَّهُمَّ اطْوِ لَنَا الأَرْضَ وَهَوِّنْ عَلَيْنَا السَّفَرَ " .
Narrated AbuHurayrah: When the Messenger of Allah (ﷺ) proceeded on journey, he would say: O Allah, Thou art the Companion in the journey, and the One Who looks after the family; O Allah, I seek refuge in Thee from the difficulty of travelling, finding harm when I return, and unhappiness in what I see coming to my family and property. O Allah, make the length of his journey short for us, and the journey easy for us. [Hasan Sahih (Albani). Abu Dawud: 2598]
