        "answer": "A direct flight from London Heathrow (LHR) to Lisbon (LIS) typically takes about 2 hours and 40–45 minutes. Return flights are slightly shorter, often around 2 hours and 30–35 minutes, due to prevailing tailwinds. With a layover, common connecting points like Madrid or Barcelona extend the journey to roughly 4–6 hours total. British Airways and TAP Air Portugal offer the fastest nonstop options."

        "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports.",
