How many days does british airways fly from Ghana to London?
British Airways offer daily "Direct" service between the capital of Ghana - Accra and London's premier International airport - Heathrow. The term "direct" has historically been used by the airline industry to somewhat massage the truth with passengers and should be noticed by anyone booking such flights. When an airline timetable or reservation displays "Direct" air service between two destinations, this does not necessarily mean NON-Stop. "Direct" means you may fly from one point to another, without having to change aircraft, or disembark from the aircraft, wherever it makes stops enroute. British Airways (BA) flight 078 typically departs Accra (ACC) at 22:40 and is scheduled to arrive at London Heathrow (LHR) at 05:25 However, there have been times when this flight operated ACC/LOS/LHR. Still a 'direct' flight, but made an intermediary stop in LOS (Lagos, Nigeria), then continued on to Heathrow. The flights presumably no longer operate in this fashion. However, historically, it has been known to happen. The flight between Lagos and London was originally part of the old British Caledonian family. The flight operated Lagos to London Gatwick (LGW), then on to Houston (IAH), with DC10-32 equipment. When the two carriers merged, British Airways were, for a period, challenged to find where the flight fit in to their new route structure. Other than the short-haul Dan Air routes, and a few other low-yield BCAL routes that fed from Gatwick to places such as Atlanta and Houston.
