True business class / upper class travelers get discounts of 20-50% for J. And no, they’re not using Amex/Chase Travel.

Corporate discounts

Huh. Where? I work for a company that's not a FAANG but $200B market cap, and what we get through Concur, Spotnana is at most, 5, occasionally 10% below what I see for the same fare class on Expedia. I have never seen anything approaching 20% cheaper, let alone 50%.
