R.34 made her first flight on 14 March 1919 and was delivered to her service base at East Fortune on 29 May after a 21-hour flight from Inchinnan. R.34 had set out the previous evening, but thick fog made navigation difficult, and after spending the night over the North Sea the airship was unable to moor in the morning due to fog. After cruising as far south as Yorkshire R.34 returned to East Fortune to dock at about 3 p.m. The airship made her first endurance trip of 56 hours over the Baltic from 17 to 20 June.
