A plane without a cargo hold?

Thu Apr 13, 2017 1:28 am

This is mostly just a hypothetical/thought experiment, so apologies for its implausibility.

Let's assume that an airline where passengers are allowed carry-on bags only, and that there is no such thing as checking bags.

Is it be possible for a plane to made without a cargo hold, and therefore be a quasi-'double decker' narrowbody with additional seats?

Right now crew rest areas kind of function like that on some planes. Could this concept be expanded?

Not sure why anyone would WANT such a thing, as it'd deny the ability to garner potentially significant revenue streams via cargo.

Second, you're just going to add weight/complexity due to the additional support and (more importantly) evacuation structures needed for a such a design.

In theory its possible but good luck with getting nobody to check bags.

Underbelly cargo is a significant source of revenue for many airlines, in theory sure the idea works fine but it would be bad for business unless your talking about a short haul concept aircraft where passengers would only need carry on sized baggage which even that is a stretch as many travelers can't go 10KM without 2 fully loaded 100L suitcases.

I'm guessing that would be many Ultralight or Light Sport Aircraft.

ATRs and Comets do not have under belly holds. They were on the main deck.

You can't just go around moving the floor on an aircraft up or down. The space that's down in the hold on a narrowbody isn't very useful for people.

If an aircraft was designed from the outset with no hold in mind, yes, you could probably make it a little sleeker and save some weight, but I think the savings would be pretty negligible.

A number of legitimate items can be carried in checked luggage; but, not in carry-on. Thus, there needs to be some checked baggage space.

Also, on a personal side my carry-on is medical equipment and supplies. My real luggage (clothing, etc) has to be checked. I can survive without a change of clothing, etc. so a missed routing is not that big a deal (it has happened twice in the last 4 years). I need my medical equipment and supplies and it is not immediately replaceable if lost. Thus, it's my carry-on. Again, you need to have space for checked baggage.
