Green Line route 724 is a bus service currently operated by Arriva Southern Counties as part of the Green Line Coaches network. It runs on an orbital route round the north and western outskirts of London between Harlow and Heathrow Terminal 5, and is partly funded by airport operator Heathrow Airport Holdings.
Route 724 was started by Green Line Coaches (then part of London Transport) on 10 July 1966, on a route from High Wycombe to Romford via North London using AEC Regal coaches. By June 1972 it had been rerouted to start from Staines and serve Heathrow Airport. The sections of route between Staines and Heathrow, and between Harlow and Romford were later dropped.
Route 724 was included in the sale of London Country North West to a management buyout when privatised in January 1988, in turn passing to Luton & District Transport in 1990, British Bus in 1994 and finally the Cowie Group in August 1996. Today it is operated by Arriva Southern Counties.
In December 1997, a fleet of nine Plaxton Prestige bodied DAF SB220s were purchased, with extra luggage space built in. These were some of the first low-floor buses to operate in the United Kingdom.
These were replaced in August 2006 by nine Mercedes-Benz Citaros. These were the result of a Quality Bus Partnership between Arriva Shires & Essex, BAA and Hertfordshire County Council. These buses seat 39 and also have extra luggage racking. Journey times were also improved.

All the Country Area and Green Line routes were meanwhile being converted to one-man operation, passengers paying the driver as they boarded, the first Green Line one-man service being the 724. This was a new route introduced in July 1966, using one-man RF coaches from the outset. Running between Romford and High Wycombe as a limited-stop cross-country facility, it proved very successful in contrast to the earlier 727 experiment.
