The switch from using Berlin Templehof to Berlin Tegel on September 1, 1975 concentrated all the remaining IGS routes at the more distant airport. Although the fleets dedicated to the IGS routes of both Pan Am and British Airways were reduced from their heyday they were still important to both airlines. The 1980s would bring about a rebirth of competition that would challenge the status quo until the reunification of Germany itself made the IGS obsolete.
IGS operations had been a close battle between Pan Am and BEA, with Air France always a distant third, despite their Caravelle service to Tegel. Flying into Templehof was what mattered and Pan Am had managed to counter the introduction of turboprop Viscounts with frequency and the lower costs of the DC-6Bs. 1966 would see Pan Am turn the tables as it introduced the first regular jet service into Templehof on IGS routes.
At the end of the 60s the age of the widebody was fast approaching and all the major US airlines were on a new equipment binge. The 747 was the first new widebody and everyone felt they had to have some or suffer the consequences of being left behind. In fact all the trunk airlines operated Jumbos (except for Northeast and Western) although, considering only Pan Am, Northwest and TWA had international routes, they mostly lacked sensible ways to utilise them. Eastern, unusually, went down a more considered path than everyone else but still ended up with 747s for a time.
The Eastern Air Lines shuttle was a pioneering idea in the busy US North-east market offering no-reservation guaranteed seat service between the super busy business destinations of New York, Washington and Boston. There are few markets that can support such a concept but travel from the UK regions to the London Heathrow was always a good contender. In 1975 the new British Airways decided to see if it could replicate the massive success of Eastern’s shuttle in the UK.
During its first 20 years of operation Ozark had fulfilled exactly the promise that the local service airlines had been created for. It had started and proved a wide range of feeder services and grown demand to the point that it could sustain not just prop-jets but pure jets as well. Even better it had done so profitably and begun to wean itself off of subsidy and pick-up longer routes that the trunk airlines no longer wanted. All in all it found itself in good position to grow into the 1970s and face the challenges of deregulation to come.
Whenever I write a history of one of my US Douglas DC-9s in 1/400 scale there is a good chance that it will have ended up with Northwest, and even possibly Delta, through the continual mergers that constituted the deregulated aviation market in the USA during the 1980s. Following the recent release of a couple of nice NW nines by Aeroclassics in this post I'll quickly look at the livery transitions many of these Diesel Nines went through.
