Air France KLM cargo volumes in the first quarter of 2019 remained static at 270,000 tons, unchanged from the same three months of last year.
The latest financial report from the European carrier said that the effect on volumes is visible across the airfreight market, due to "economic slowdown, political uncertainties and trade disputes".
This put pressure on freight rates, resulting in a fall of 4.0% in unit revenue per ATK at constant currency.
A spokesperson said: "Several network rationalization measures have been implemented during the quarter to counterbalance the negative trend.
"A slight capacity increase has been offset by this unit revenue decrease, resulting in a decline of revenues by 1.3% at constant currency [to €547m]".
