By the end of January 2010, Dnata was the proud owner of Plane Handling Ltd, formerly part of the Go-Ahead Group. It provides cargo and ramp handling services at London Heathrow Airport and cargo handling services at Manchester Airport. Dnata has also acquired passenger and ramp handling operations at Terminal 3 & 4 at London Heathrow Airport from Aviance Ltd, which is also part of the Go-Ahead Group.
