As Air Arabia Maroc is a JV/subsidiary of Air Arabia, have you tried booking on the main site ? I just tried and can select flights, get prices, etc.

In case you weren't aware, Air Arabia is a well-known and established Gulf LCC based out of Sharjah (SHJ) which is next door to Dubai. I've flown them numerous times.

If the aircraft are operated by Air Arabia, I'd have no problems flying with them.
