I think the 748 fleet became somewhat mixed after the merger. Skyways operated from Lympne (pronounced "Lim") airport, alias Ashford, which was a grass runway, and the 748 was about the largest type that could operate there. I believe Skyways physically owned it. When periodically waterlogged, or after the merger when larger Viscounts took over from the 748s, things were transferred down the road to Lydd. This was aided by their principal traffic being London to Paris "Coach-Air" services, with road coaches from each side. The 748 seated 48, which was the same seating capacity as typical road coaches of the era. They also did quite a lot of holiday IT charters on the same route for travel companies doing coach holidays to the continent. Their several 748s were notably intensively used shuttling to and fro on summer weekends, the scheduled service alone being roughly hourly. Lympne, despite being grass, must have had full lighting, because they scheduled to operate until midnight.
The original 748s transferred to Dan-Air were some of the first built, for Skyways in 1962, and after the 1973 merger then had amazingly long lives with Dan-Air, some through to 1990. Regarding livery consistency, well, this is Dan-Air. Were any two aircraft ever painted the same ?
. The 748 fleet at both organisations was notably fluid, with aircraft leasing both in and out. Skyways, being a very seasonal operation, worked significantly in this way.
The 748s, pressurised and on a somewhat longer run, flew over the top of the Silver City (later BUA) car ferry shuttle's Bristol Freighters operating from Lydd to Le Touquet.
Skyways were an absolute pioneer independent from the end of WW2, and in the early 1950s one of the largest. They started the Coach-Air operation with DC3s. The mainstream airline eventually morphed into Britannia Airways (I'm shortcutting notably here), while Coach-Air continued with the name as a separate company - they probably always were required to badge as Skyways Coach-Air. After selling out (maybe for £1 - plus all the debts) to Dan-Air their longstanding MD retained a few all-cargo DC3s, which ran on for some years in the 1970s, separately again, still from Lydd but also inevitably at the time from Aberdeen as well, often indeed in competition with Dan-Air there, before finally closing down in the early 1980s.
