They're undoubtedly planning to at least build some luxury cruise models, but I'm thinking more. For one thing, Boeing picked up the funding for a couple of companies doing research on modern airship construction a couple of years ago. That says a lot, seeing as how Boeing has been strictly an airplane company through the years. Not to mention the fact that, despite plenty of prospective blueprints, they chose to go with smaller, twin engine wide bodies with good fuel conservation stats. And the next prospective giant they have been considering building for quite a few years now, is a blended wing body with hybrid, pusher prop/turbofan engines. I take all of that as an indication that passenger service airships are in the works. How far along the process might be is anybody's guess, but don't expect them to look like traditional airships, because that probably won't be the case.

Materials technology has always been a major drawback for airships, but that is changing rapidly now. I believe that it's reasonable to expect to see a company come out with something that looks like a giant wing. Maybe as much as seven or eight hundred feet across, and eighty to one hundred feet wide. And vacuum lift. Look for the next lifting gas to be a vacuum, whenever they crack a couple of problems. Nothing is lighter than a vacuum, so an airship that uses a series of vacuum filled cells for lift would be able to carry very heavy loads. Especially if they heat the vacuum. Plus, that adds the possibility of using Hydrogen for fuel. Hydrogen wouldn't be volatile at all, if it was carried in a bladder, that was placed inside of a vacuum filled tank. That removes fuel as a part of the load. The fuel would then be a part of the lift.

Yes, I'm pretty sure that there are aerospace companies all over the place who are tackling these issues. Lockheed has even built one:
