Most arrivals are from the North. This usually results in a "Konba" arrival or similar. If TFS are landing on runway 26 the arrival routes down the western side of the island then along the south coast to intercept the localizer for Runway 26.
Clearly if you were arriving from the East or North east the arrival would bring you via Gran Canaria for a downwind arrival to Runway 26. It may well happen that some flights route via other islands or from that direction generally.
