Hi everyone

Trying to book the following fare on the Emirates website but it seems to hang up on the final screen (i.e. the screen before you are shown the fare).

Route
PVG - KHI - GLA - PVG

I've tried both from a computer and the iPad app but getting the same issue. When I call Emirates, they say I can't book this as one booking (hence why im having issues on the website) - it will be two separate bookings due to the Karachi stop over. Problem is, i'm sure i've done this before via the Emirates website without any issue. Is what EK telling me true or have the recent changes on EK mean i will need to make two separate bookings?

Thanks in advance.
