A British Airways Boeing 787-9, registration G-ZBKL performing flight BA-243 from London Heathrow,EN (UK) to Mexico City (Mexico), was climbing out of Heathrow's runway 27R when the crew stopped the climb at FL100 reporting a problem with their slats. The aircraft descended to FL080, positioned to the Bristol Channel to burn off fuel and positioned for the approach to Heathrow's runway 27R about 2 hours later. On approach the crew advised, they did have problems with their slats and needed to fly the approach at a higher than normal speed, their final approach speed would be around 185 KIAS. The aircraft landed safely on runway 27R at a higher than normal speed (about 180 knots over ground) about 2:10 hours after departure. The aircraft was checked by emergency services before emergency services were stood down and the aircraft taxied to the apron.
