Right, no doubt the prices you mentioned are valid, but for domestic flights. I mostly fly transatlantic with Delta, that's why the upgrade (and its associated costs) is not a no-brainer for me. Also, I only snagged the exit row seat for the return flight. I don't qualify for Diamond level with Delta, as I fly with several different airlines (non-Skyteam). With Delta, I do qualify for 50% discount on upgrades, I listed the fees that basic members would pay.
