Hi, apologies if this should have been discussed at length before.
To my knowledge, LH is the only airline that has fitted its A340-600 aircraft with lower deck lavatories in order to increase seat capacity (LH is also the airline with most pax on this aircraft type). Obviously, other operators of that type are not interested in this configuration.
But why aren't there any other airliners that can be equipped with lavatories on the lower deck? I'm especially thinking about the A330, which is identical to the A340 in many aspects.

On the A330s and A340s equipped with lower deck lavs, are the lavs accessed by a stairway or by an elevator? Also, are all the lavs on these aircraft on the lower deck, or are there still some on the main deck as well?

Lavatories on the lower deck are accessed by stairs and are for economy passengers. Business and first class passengers has their own lavatories on the main deck.

Quite simply because it eats up cargo capacity, yes you gain some more seats upstairs but the cargo loss is probably greater, especially if you also want the lower deck crew rest as well. The charter companies don't rely on cargo so that's why they have it installed and in LH's case only on the -600 because it's big enough to do both. Virgin, in typical fashion, promised lower deck sleeping cabins for upper class when they first ordered the -600 but (sensibly) realised there was more revenue in cargo down there.

Quoting Wingtips56 (Reply 11): It's unlikely a U.S. carrier would have lavs downstairs because of the A.D.A. Disabled people would not be able to use them.
I doubt that would be a problem provided there was at least one lavatory on the main deck which disabled passengers could use. That's the case on LH A346s which have one Y class lavatory on the main deck in addition to the 5 downstairs. And the 2 F and 3 J class lavatories are all on the main deck.

Quoting mickey90 (Reply 3):
Thomas Cook Scandinavia also has lower deck lav's on their a332 but not on their a333 as far as I know. I once flew with their a332 from GOT to CUN and thought it was a cool option.
The former MyTravel A332s all have lavs downstairs which occupy Hold 3, and leaves space for only 7 LD-3s in Hold 4 (only if the rear LD-3 in part of Hold 5 is fitted) - the other Thomas Cook a/c have the lavs in the cabin. The lavs downstairs were thought to increase seat capacity in the cabin, and are accessed via a stairway - only issue is there is a requirement to have 1 of the cabin crew downstairs to ensure nobody falls!

In my opinion as a frequent economic fare traveler, it's much better lavatories in the lower deck in order to avoid annoying odor coming from the lavatories. Although I know airlines don't care about that but LH and some other.......

There is that.
In my opinion, the biggest additional advantage of the downstairs lavatories is that they reduce waiting times. In a normal upstairs lavatory configuration, there's two or four lavatories or groups of lavatories. If you end up waiting in queue for one where someone is taking a long time, you'll have a long wait. With all the lavatories grouped downstairs, everyone is in the same queue and random variation in the waiting times averages out.

Actually, since I once flew Economy on LHs 346 and know about the Lavs, when I fly Business, I still use the Economy Lavs downstairs (of course not in high frequent times).
I think the downstairs ones are better then LHs Business Lavs.
With the LAVs LH also has the Crew Rest and the ECO Kitchen down there. Food comes per elevator of course.
There is no one placed there to whatch downside, but one FA is around and from time to tome checks that there are not more then a no of passengers there (I think 5 or 6), due to oxigen masks limited.

I have flown the LH 346 with the downstairs lavs. And it is correct that there is one at the rear of economy for disabled passengers.
While I think in theory that it's a great idea, in practice there are some problems. On one particular flight, there was the strong smell of urine downstairs. I wondered if there was an issue of the ability to properly clean that area or if there is inadequate ventilation. They have a small alcove where they put out some crackers.cookies for snacks and encourage people to stand down there around the toilets for passengers to stretch their legs. Ugh! There really is no other place to stand. The seating comfort on the LH A346 is seemingly the tightest in their fleet and if you sit on the inside of the four seat section, you really need to get out, especially if the person in front of your reclines his seat...and they always do. But, I have to admit that stairs in an airplane, A346 or B747, is kinda neat.
