I booked a mixed cabin fare this week but it was strange and they wouldnt let me do it on the phone.

I found online Emirates that I could for LUN to MLE, Lun sector Business and MLE sector Economy. Then I booked MLE to YYZ, the DXB econ and the YYZ Business.

The guy on the phone said it wasnt possible as emirates wont booked mixed class fares, then when i went back to try on the website it gave me an error. However, i cleared my history and went back in, and the website let me book a mixed fare.
