Which is why BA, LH, QF, CX are removing F seats from their flee, because demand is going u-wait, what? You mean a lot of airlines are removing first class from a number of their planes? That aren't USA-based airlines?

Additional fun fact: airlines are finding that Y+ cabins (real premium Y+, not E+) actually make more money per square inch than F cabins- they are the most lucrative cabins they can offer. Not coincidentally, airlines like CX and QF are going from F/C/Y cabins to C/Y+/Y.

The fact of the matter is the F cabin on a lot of airlines is like the joke about the million dollar glass of lemonade- "I only need to sell one!", with employees/upgraders/FTers who have figured out the latest arbitrage scheme rounding out the cabin. A lot of airlnes have figured out that offering products that consistently sell and fill the plane is more profitable than trying to sell that million dollar glass of lemonade, while incurring the costs of stocking caviar, JWB and Krug. And the fact of the matter is C/J now has a hard product that blows away the F of 20 years ago. Why not pay for your Michelin cuisine on the ground instead of at a 10x premium (and blast-chilled/reheated to boot) in a hurtling aluminum tube, eat and drink something that is simply edible/drinkable instead of a fake gourmet experience, and use the plane to sleep and watch some TV in reasonable comfort?
