I dont know about AF,but i can confirm that Ib**** do/did.Whilst Despatching in the early 90s i used to see the crew on turnaround having the standard bottle of wine or beer with their meals.
Anyone from our Spanish friends wish to comment??.
The company I worked for did A.C.M.I. flights for Air France Cagro in 1992/3 all AF flight numbers and the crew meals always had a small bottle of plonk with them.
Straight into the nav bag and kept for the night stop.
