I was recently reviewing my first booking for flights with Dubai connect and the Qantas site showed various buttons... QEats, Dubai Connect, Chauffeur Drive. (these were not greyed out but available to be clicked on)

On clicking the buttons the system would think for a bit before a response would come back 'you flight is not eligible for Q Eats' or 'your flight is not eligible for chauffeur drive'.

We subsequently changed a couple of flights when availability opened up and the same buttons appear but now show the relevant flights in a drop down list.

So it seemed at the time that you need to click through in order for the system to tell you if you are eligible.

But that's only a data point from a single booking.
