In WW1, once Britain developed effective means for shooting down airships, the Zeppelin company built lightweight airships that could climb as high as 20,000 feet, at the cost of being too fragile to handle rough air. Outside of the exegencies of war, these were not viable designs.
Being limited to low altitudes means that practical airships cannot fly over the weather, and their low speed limits alternative destinations. Three of the four helium-filled rigid airships operated by the US were brought down by bad weather. These days, we have much better materials and weather forecasting, but I think operations would still be quite frequently constrained by the weather in most parts of the world.
On the other hand, if the stream of powered sightseeing aircraft over the Grand Canyon could be replaced by a few electric airships... Well, we can dream.
