Passengers received an average of 39 days’ notice of changes or cancellations in 2022 – compared with 54 days in 2019.
The proportion of travellers who experienced flight cancellations or changes prior to their departure date remained higher in 2022 than pre-Covid, with 40% of passengers affected, compared with just 25% in 2019.
Emilie Dumont, managing director of travel provider Digitrips, which carried out the research, said: "This year is likely to be even busier and, with staff shortages and strikes continuing to cause disruption worldwide, we expect the cancellations window to shrink even further.
