Gatwick Handling was originally started in early 1972 as a 50/50 partnership between Dan Air and Laker Airways to handle their operations at LGW, the company started to pick up third party business from other airlines and therefore expanded. After the collapse of Laker in April 1982 Davies & Newman the owners of Dan Air acquired total ownership and continued operations.
Shortly afterwards 50% of Gatwick Handling was purchased equally by Delta and Northwest.
In 1992 after British Airways purchased Dan Air Gatwick Handling was owned 50/50 by Delta and Northwest.
In 1998 the Go-Ahead Group purchased the company from Delta and Northwest.
In 2000 Gatwick Handling was merged with Midland Airport Services and REED Aviation to form Aviance.
In 2009 Plane Handling the parent company of Aviance UK was sold to Dnata Handling which still exists.
So in one way or another Gatwick Handling still exists but is now owned by Dnata, quite an interesting history of that original company.
