Very interesting email. The previous QF BA agreement was a revenue sharing agreement, so it did not matter physically which aircraft a passenger on the route travelled on.

I don't believe the QF EK agreement is revenue sharing, instead a "catch what you can kill" agreement, where the aircraft operater receives the lion share of the revenue. And this is the result.

I am guessing that the recent comments by Emirates about how they have received an increase in revenue F and J passengers under the new QF EK agreement will have irrirated QF to no end.

On ports that they travel to, like London, QF will want those passengers on its planes. Interesting that they are targeting passengers whose airport origin is also different, ie targeting Gatwick passengers and trying to put them on QF Heathrow flights.
