Would a seven hour flight rather be done on an A321 or a NMA?

Re: Business Risk for Boeing: The A321XLR

The new A320 will create many new point to point destinations. For people like me liviing in Stockholm i suppose that connections that I needed to thru hubs now might become connection directly from ARN. Transatlantic market will change. IMO the collateral victim of the A321XLR will be the 777X and...

Re: Why is the A330 still in production but the 767 isn't (for pax)?

A300: first flight 1972 with around 220 kN engines. B767: first flight 1981. Surprising the engines didn't really become stronger. A330: first flight in 1992. Engines somewhere around 311 kN. Moreover the A330 got the long wing from the A340 and has lot of space for cargo. Should the B767 be compare...

Do manager bonuses harm aviation?

Manager boni are meant to motivate managers to do their best. However boni depend on short term profits. The higher the current year's profit, the higher the boni. Suppose a company has a headquater which it built 30 years back. Selling this headquater and renting it back leads to a jump of profits ...

Re: Narrowbody vs widebody costs trans Atlantic

If a plane is not loaded to MTOW one could argue that the added cargo only cost a little fuel. Actually, I don't know how much of cargo revenue is pure profit. Does cargo not have a handling cost? Does it not need marketing and accounting and people to load and unload and wearhouses to wait for shi...

Re: Tim Clark: Emirates is planning its network without the A380

The last major world recession was in 2008. We may be overdue for another, triggered by disruptions and rising oil prices, Brexit and who knows what.

Re: Narrowbody vs widebody costs trans Atlantic

Since you’ve posted the LH numbers, have you checked what their annual profit was in 2018? If you subtract the cargo ops from the overall profit then it shows how important cargo actually is. The first link I mentioned says Konzernergebnis (=profit) is 2,163 billion Euro. Turnover from cargo was ar...

Re: Narrowbody vs widebody costs trans Atlantic

However, as others have said, you also need to factor in cargo - widebodies will carry a lot more cargo than a narrowbody, which will further offset the costs. You are forgetting the revenue side of things, there are a lot more premium seats in a wide body and a lot more cargo space. Don’t forget w...

Could this be a favour to Boeing to bring back some confidence after all this bad PR? That was my thought for a moment as well. But why would LH of all companies do that?

Re: "Safety is our Highest Priority"

If “safety is our highest priority” we’d leave the planes in the hangars, the cars in the garages and the boats at the docks. Safety is reward vs. risk assessment, not an absolute. GF One can put a price tag on crashes - and it quickly turns out it is cheaper to pay for high safety standards. Cost ...

Re: Optimum materials

When the B787 was relatively new I asked a stewardess what she thinks of the plane. She said she loves it. For the fuselage carbon fibre is good because lack of corrosion allows for greater humidity in the cabin. Carbon fiber is strong, but only in direction of the fibers. Obviously there have to be...
