 BUA's attempt to have British Eagle stripped of its licences to operate scheduled services on the three main UK domestic trunk routes resulted in the latter's decision to resume operations on Heathrow—Glasgow on 5 July 1965, at a frequency of three return flights per day.Two of these operated non-stop while the remaining one routed via Liverpool.Combining its licences for unrestricted frequencies between Heathrow and Liverpool, a maximum of two daily return flights on Heathrow—Glasgow as well as 17 weekly Liverpool—Glasgow round-trips, enabled British Eagle to operate the Heathrow—Glasgow route at a higher frequency.
