Some rumours I am picking up is that Niederrhein may be a candidate. NRN has 24hour operations, can handle everything including 747s (!) and has loads of space to build warehouses.

Strangely the standard of seats in Economy varied between forward and rear cabins.

PH-BFR is a combi plane. Perhaps the seats in the first half of the plane are the fixed seats, with the last half filled with palletised seats. The seats on the pallets would probably be damaged sooner because they are pulled in and out of the plane whenever required.

Excellent report, that looks like a decent size viewing deck at Schiphol.

Those shots have not been taken from the viewing deck. They have been taken airside through the windows. But, Schiphol does have a massive viewing deck.

…any idea what percentage of the KLM fleet has had the modified livery applied to date?

B737-300 … … 8/14 … … 57%
B737-400 … … 6/14 … … 43%
B737-800 … … 5/13 … … 39%
B737-900 … … 1/5 … … 20%
B747-400 … … 7/22 … … 32%
B747-400ERF … 3/3 … … 100%
B767-300 … … 2/12 … … 17%
B777-200 … … 7/7 … … 100%
MD-11 … … … 2/10 … … 20%
all … … … … 41/100 … … 41%

hmmmm, is this real? The photo seems to have been photoshopped. The spray is real but I have the impression the waterpool on the lower half of the picture is fake.

Yes and Martinair is another with 762’s with only two doors!

All Martinairs 767s are ‘300s.

SABENA: Such A Bloody Experience, Never Again!
SABENA: Swissair A Bien Encaiser Notre Argent (swissair happily cashed in our money)
SABENA: Searching All Bags, Expect No Arrival.
KLM: Komische Landings Methoden (comical landing methods)
VBird: Very Brave In Remote Deutschland
Dutchbird: Delivering U Tremendously Complete Holidayflights, Barely In Real Danger.
Ryanair: Really, You Are Not Actually In Rome!
Schalks: Should Complete Historyclass At Local KLM Serviceagent.
Martinair: Might Arrive Really Timely, Interestingly, Never At Intended Runway.

It is a lot busier in the corridors, but everything is together. This makes it easier to guess each others intentions. The ATC and other pilots will know what other planes are (going to be) doing because there are fixed patterns.

It is also important to remember that not everywhere there may be radar coverage. The flight lanes do have radar coverage. Same goes for beacons, ATC communications etc. In particular the flights over the oceans you mentioned suffer from this problem.

Another advantage is that small planes will know where the large planes are. Therefore it is possible for the small planes to avoid them, and their wake. Most small prop planes do not have radar and depend on the eye and ATC to prevent collisions and wake turbulence.

Finally, a lot of areas are forbidden for airliners. For instance military training grounds and airspace over critical installations like nuclear power plants and in many countries the parliaments/palaces.

There probably a more reasons too that pilots will get into.
