بسم الله الرحمن الرحيم
(Fatwa: 1381/927/L=11/1434)
It is not lawful to combine two salahs in a journey and offer them together. Each salah should be offered in its time. If two salahs are to be performed together then its method is that Maghrib is offered in its last time and Isha is offered in its starting time, then tarawih should be offered as per the capacity.
Allah knows Best!
