It’s usually perceived as mid-to-upper range on fares, with a wide choice of lounges and services for business travellers. Located about 25 km west of central London, typical transport options include the Heathrow Express to Paddington (15–20 minutes, higher fares), the Elizabeth Line (25–30 minutes, moderate fares), London Underground’s Piccadilly Line (50–60 minutes, budget fares) and taxis or ride-hail (30–60 minutes depending on traffic).
