Unions representing French pilots and cabin crew have announced a four-day strike against government plans to tax various job-related perks.
Strikes against pension reforms hit domestic and international flights last Thursday.
The main union of pilots says legislation being discussed in the National Assembly would make perks, such as reduced air tickets, hotel room rates and airport parking, subject to tax.
SNPL France Alpa called on the government to cancel the proposed legislation.
Unions said the strike would start next Friday and run until Monday, 8 November.
