We, the company, doesn't really care what type of aircraft your currently flying, only that your experience fits into certain groups. A330 is a group "D" aircraft at Saudia, along with the 747, 777, and 787. A340 would be considered group "D" experience, so it qualifies you. Regardless of the aircraft you're on now, the one you get trained on here may or may not be the same. A full course is required regardless, but without any bonds.
