323. Salaatul Travelling

You will shorten all the four rak’aat prayers to two. 

And the Prophet sal Allaahu Alayhi wa sallam did not read the Sunnah associated with the five daily prayers while traveling except the Sunnah of Fajr and witr. 

So Fajr stays the same. 

Dhuhr is only two rak’aat. 

Asr is only two rak’aat. 

Maghrib is three rak’aat. 

Ishaa is two rak’aat plus witr. 

And Allaah knows best
