All of the activities of the airship were considered interesting by the newspapers. The New York Times had 5 or 6 articles on the Hindenburg in April alone. The Hindenburg was by far the fastest way for a passenger to cross the Atlantic at the time, taking only about 70 hours (3 days) compared to regular ships which took about a week, twice as long. It's passages were keenly watched for "speed records". At the time, the line was promising to expand to a regular passenger schedule, and this was to be the first of such crossings, which promised to usher in a new generation of fast cross-Atlantic travel. The second flight in this new "regular" schedule was expected to bring newsreels of the coronation of King George VI and Queen Elizabeth, a highly anticipated event by the American public, which increased the interest in this precursor flight.

A more general answer can be given. Transatlantic flights of airships were rare events. No comparison with modern airplane fights, and with regular ships crossings at that time. So it is not surprising that they had attention of the media. And they were available mostly to the "rich and famous", and these people always have attention of the media whatever they do. (The ticket for Hindenburg was $400 one way, which is very expensive!)
The regular passenger transatlantic service by airplanes was established only in 1939, according to Wikipedia.
There were two or three airships performing transatlantic flights regularly, and the total number of their flights was less than the number of manned space launches up to present. Space launches still call for media attention, especially the manned ones.
