RUH-LHR return Business. Outbound the business and first class check in is mobbed by economy passengers asked several staff to be checked in as I was in business class and told to wait - after 45 minutes I demanded to be checked in as flight was closing to be told by the same Saudi staff I didn't you realise your were business class. Flight out fine Asian staff friendly and obliging the Senior walked around the cabin with a scolding look on his face. Return much older aircraft seats dirty and did not recline food dreadful cabin looked filthy staff cold rude and didn't care less that 3 kids running around the cabin actually slapping other passengers as their parents did not care what they did. The final straw IFE not working. Airline gets worse every time I fly with them no more.
