Labour day – a national public holiday in the United States –  had a clear impact on the air cargo volumes for the week of Sep 7 -13. The volumes from United States to Western Europe dropped by 14% versus the previous week, resulting in the dynamic loadfactor for flights from the United States to The Netherlands to fall from 67% to 62%. But this loadfactor moved up quickly again last week, to the pre-holiday level of 67%.
