For the passengers, yes they are. For the holding tank, not as much. :)

Having been to Newark rather too many times, I totally get it. :)

The standard one is fine. The A350 already routinely flies 16 hour sectors.

Singapore and NYC are two of the perhaps top 5 financial centers in the world. Lots of traffic.

From my above post:

Don’t forget the incessant drone of the radial engines...

Helpful taxi drivers in HK? What sorcery is this? ;)

We carry a body bag on all our aircraft. It’s a regulatory requirement.

Airliners are pretty efficient. :)

Heh... Thankfully lavatory air is not recycled like the rest of the cabin air. On a modern plane it’s quite hard to get a whiff unless someone has gone full Jackson Pollock in the lav.

I hear you...

I’ve operated all of one trip with 16-hour block time each way. Even with four crew, the crew bunk, the comfy seats at the pointy end, and the northern lights on the way back, I was cooked at the end. Bored to tears. For about 6 hours over the pole there isn’t even the occasional radio call to stave off…

When I was in my early 20s I’d fly Europe to LAX a few times a year in economy. No big deal. 20+ years on, my body seems... changed into one that is no longer quite as tolerant... :)

Fair dinkum.

Air inside the cabin is recycled every two minutes to make flyers more comfortable and cut down on the effects of jet lag, Airbus claims.

We do 15+ hour flights with our “non-ULR” 350s. 270+ passengers. The waste tanks handle it fine.

The one bright spot in an otherwise terrible movie. :)

We still do the occasional take-off with packs off for performance reasons. Hot weather, short runway and high weight all have an effect.

Poo and pee are not dumped in flight. 

In my experience, a 1h35m connection at HKG shouldn’t really require any rushing. Was there a long line at transfers?
