Shortening & combining prayers while travelling?

I saw a hadith Narrated Ibn `Abbas:
"Allah's Messenger (ﷺ) used to offer the Zuhr and `Asr prayers together on journeys, and also used to offer the Maghrib and `Isha' prayers together. Narrated Anas bin Malik: The Prophet (ﷺ) used to offer the Maghrib and the `Isha' prayers together on journeys"(Sahih al-Bukhari 1107)...based on this, is it always permissible to join prayers while travelling or is this only permissible in Muzdalifah & Arafat because there a hadith where Ibn Masud said "The Messenger of Allah used to offer prayers at their proper time except in Jam (Al-Muzdalifah) and Arafat."
(Sunan an-Nasa'i 3010)

Or is this based on a different context?
