The findings come from a new report by the Scottish Passenger Agents’ Association (SPAA), which also showed 26% of departures are in the next six weeks.
The majority of travel is to Europe, but both the US and the Caribbean are the next most popular destinations.
However, the survey also showed SPAA members are still facing many hours of additional work in relation to last minute cancellations, heightened for Scottish agents having to accommodate connecting flights through London.
