There are a lot of perks even when you don't get an upgrade. The intangibles (being taken care of when issues arise — I've received amazing service, even when the issues were my fault) are invaluable.
Domestically, business is usually 3x. I just booked my first ever paid-for-with-real-money business class domestic flight SFO-CLE for thanksgiving; it's not that it's cheap, it's just that thanksgiving demand drove coach fares up so much that business starts to look reasonable -- 1500 vs 750.
The perks are invaluable? No, I think they can be valued, and I don't think hardly anyone paying their own dollars values them at even the price the airlines ask for, let alone infinite.
My friends who travel to China on company business brag about "only" paying $3000 of company money for Business because they have such discounted fares through their employer, where it would normally cost $5k. $1900 is virtually unheard of, congrats to you, but it's far from normal.
Take your pick of dates on the calendar: $1,900 to $2,200 is available pretty much any days.
Sure, it takes a bit of knowledge and research to find the good deals, but there's almost always a way to cross an ocean round-trip at around $2k.
