I find cheap direct flight going from london to marrackech but not casablanca , after British airways stop going to morocco casablanca , i start going by easy jet or rynnair but only to marrackech,as other flight are very expensive.

Chosen Answer:

Royal Air Maroc fly direct to Casablanca from London Gatwick & Heathrow. However, their cheapest flight is from Gatwick to Casablanca, with a stop at Marrakech, which is available with an Economy relax fare.

An alternative that might be worth looking at is by flying from Gatwick to Marrakech with Easyjet & then taking a flight from Marrakech to Casablanca with Royal Air Maroc.
