The presence of Dan-Air, a major scheduled and charter operator at Gatwick and Manchester, Air Europe's two largest bases, meant that Air Europe was facing a potential competitor for every additional scheduled service and charter contract that became available. Dan-Air's large-scale presence at Gatwick, the airport's increasing scarcity of early morning peak time slots, and the fact that Dan-Air had already been licensed to operate scheduled services to some of the destinations Air Europe wanted to serve as well while only a quarter of London's and a third of the entire Southeast's population lived in Gatwick's catchment area also meant that attaining the "critical mass" to make its scheduled operation viable became an uphill struggle for Air Europe. This situation was made worse by the state of the British economy in the late 1980s, which was overheating and going to give way to a major recession during the early years of the following decade.
