I have a question if it is possible to set up an alert to tell if a certain fare bucket is available when that flight is booked as a combination with another flight? Maybe I didn't word that correctly, so here is an example...

I want to purchase an I class business fare on Emirates (EK) from CAI-DXB-AKL on the 22nd of Dec. If I search CAI-AKL on ExpertFlyer for departure on 22nd Dec, the 3 flights are shown, and I class is zero for all (EK flies from CAI via DXB and then SYD, MEL, or BNE to AKL). So, that's fine. However, if I make a flight alert for any of these flights (DXB-AKL via SYD, MEL, or BNE) for I class greater than 1, it immediately tells me that the fare has been found. This is because if you search for I class DXB-AKL on the 22nd of Dec, there is a lot of availability on any of the three flights. EK is limiting the I class for bookings originating in Cairo, but not in Dubai, for their flights to Auckland.

So, can I set up an alert that will tell me if I class is available on DXB-AKL when I am flying this leg as a part of an itinerary that originates in Cairo?

Sorry for a complex question. I use ExpertFlyer a lot, but couldn't work this out...
