Saudi Arabian offload boeing- MD aircraft

Saudi Arabian Airlines has put more than 40 of its aircraft up for sale including most of its older Boeing 747s and practically its entire Boeing MD-90 fleet.

The Jeddah-based flag-carrier is offering 28 MD-90s as well as nine 747-300s and five 747-100s. All the aircraft are owned by the airline

This is following an agreement for up to 50 Airbus A320`s with options on other types to replace the 747`s.

From what i understand there are actually alot of MD-90`s now on the market , is there lack of confidence in the type now?
