EUROCONTROL Data Snapshot #26 on how all-cargo flights complement passenger flights

Our data

Our 26th EUROCONTROL Data Snapshot is here, focusing on how all-cargo flights increasingly have two peaks in demand each day, but this complements other loads on the network.

Flights by all-cargo aircraft (‘cargo’ for short) complement passenger flights in a couple of ways. First, they carry around half of air cargo, while the rest travels in the holds of passenger aircraft. What is less well known is that cargo flights have two busy periods, just before the passenger day starts in earnest, and just as the passenger flights are finishing for the day. So their demands on the network, which are light as cargo amounts to fewer than 3% of departures (2019 statistics), complement the demands from passenger flights.

The graph shows the pattern of flight departures by hour of the day (in local time), for example 6% of cargo departures are between 03:00 and 03:59. This is an average for the whole of 2019. Cargo departures have a peak in the 04:00-04:59 slot, decline to a low point in the middle of the day, then climb to a stronger peak in late evening. This is the converse to passenger flights (and even more so to business-aviation flights) which really start in earnest from 06:00 and are relatively high all day, before declining from 20:00.

The 04:00 peak is so strong that, in 2019, even if cargo amounted to only 3% of departures overall, it had the largest share of all flights in that slot with 20,300 flight departures (56 per day) between 04:00 and 05:00, versus 11,000 (30 per day) scheduled passenger departures.

Even though 2021 was disrupted by COVID-19, the variation during the day was not that different; some of the peaks were just a little lower. There has been more change over the longer term. Since 2005, with the rise of overnight delivery, both the morning and evening peaks have grown sharper, up 2.2 percentage points in the morning, from 6.2% in 2005 to 8.4% in 2019, and 1.5 points in the evening, from 8.6% to 10.1% in 2019. Both the middle of the day and the middle of the night had a smaller share of all-cargo flights in 2019 than in 2005.
