They have the data already of the max price customers will pay

Why the downvote?

You can fly to the EU for 600 USD (retour), more in high season. Non business people are willing to spend 1200, 1400 USD. I assume around 2000 USD the demand will fall off significantly. At 5000 USD for economy it will be close to zero.

		I just booked for the fall to London. Roundtrip was around $1200 from eastern US in economy with a couple of minor upgrades which is high but not ridiculous. The increment is basically a couple nights of hotels and meals. I've paid more; I've paid less. Was going to take ship back but it wasn't available for one person.
