Yeah ok i need to make the point i thought was obvious.
UV as well as ionizing radiation are the same per hour no matter the total length of the flight.
So unless ultra long haul makes pilots sit in the cockpit longer PER MONTH it just has nothing to do with this thread.
Also i guess they should just be offering free Aspirin prior to these long flights might cut the DVT rates significantly.

I flew the TG BKK-LAX route a couple of times on the A340-500, enjoyed it. My recollection is that the fuel costs were the problem. Are the fuel costs for the same number of people reduced for the same route with the A350 based on the magic of modern technology and number of engines? If so, I can imagine a non-stop out of Singapore or another hub making a lot more sense to people who just want to get it over with in one go.

The issue is around how long crews spend at higher cruise altitudes over the period of a month. With more 787's, etc. at FL410/430, exposure at that altitude has to be more than at FL350. Exposure on shorter sectors where the aircraft spends more time at lower levels or on the ground is not as serious..

I would think for this sort of sector length of 19-20 hours the minimum acceptable standard of seating would be 38 inch pitch and 8 across. Anything less would be unbearable.
I've done the Europe to Oz trip more times than I care to remember. Each trip I had to disembark go through the whole rigmarole of collecting my precious things and then after killing an hour doing nothing, get back on and reacquaint myself with all the silly nonsense I had the first time. Another cabin briefing, another crew telling me how delighted they are to have me on board, another enroute/destination weather report...etc, etc.
Just get me there please!!!
Bring it on I say again.

One of the (unintentionally funniest things I've seen on long distance travel was Richard Quest breathlessly and enthusiastically interviewing punters on the inaugural SQ A340-500 SIN-EWR flight ..
As the flight progressed they were less and less inclined to speak to RQ until at the end of the 18 hour ordeal, pax after pax hurriedly brushed past him, desperate to get off the flight. Quest was desperately trying to get someone to talk to him, a few words from a seasoned traveler...but no. Not a peep.

Does anyone know what the relative fuel costs are for one-stop vs. non-stop flights.? I can imagine that flying directly over an intermediate airfield at FL 400 will use less fuel than descending then climbing from that airfield... but... Obviously the non-stopper has to carry about twice as much fuel in the first place.

Have a read of this thread: ULH flights burn much more fuel

Once, long before I retired and still had the data, I calculated the fuel burn penalty of one 8000nm vs 2 x 4000nm as about 10%.
Take into account that posters suggest a seat needs to occupy 20% more floor space to be acceptable ....and all the ULH problem is there ...

Thanks Oldchina, so that is 10% more cost for the fuel, but a saving of chargeable time, and intermediate Landing Fees, which could be financially crippling if the intermediate airfield was London Heathrow.

Flying non-stop and having to carry all that extra fuel from the origin airport could result in being payload-limited.

Thinking on... there are so many other factors to be taken into account. If the direct flight takes about 20 hours, you can do the same schedule the very next day, but if the double flight takes over 24 hours then the following flights will not fit into a daily schedule. Aircraft only make money whilst they are flying, not whilst they are on the ramp or taxiing.

You're probably wishing by now that you hadn't asked.
By the way, did you read that link I gave you ?

As a customer who does at least one long haul a month, if not more I personally prefer a non stop as it allows me to arrive with some semblance of rest. Get on board get comfortable ask not to be bothered & go to sleep. Arrive with at least a few hours of shut eye & it helps the jet lag both ways... Added bonus is if/when I get to fly business then it is really a beauty. I hate the one stop flights as each segment does not allow more than a 4 hour rest given all the service shenanigans on both side of departure & arrival. Actually a total waste of a business class fare where you just cannot get a full 8 hours of shuteye. I always opt for the Long Haul over the hopping flights...That said longest I have take is about 16 hours.
Price points in Economy tend to be about +25% Different & in Business about +18% or so (When comparing hopping to nonstop).

It is still worth paying the amount as it gives me an extra day with the family awake on each side.
Sounds crazy but yes there are paying people like me out there who lead such a commuting life in the quest of having the best of all worlds.
On a two-leg journey, a greater proportion of the overall flight time will be spent at lower altitude, in the climb and descent x 2, where the solar radiation effect is less. I think we need to see the sums.
