✈️ Flight Guide: Newark (EWR) → London (LHR)

London: London Fashion Week (usually mid-September) and Open House London (mid-September weekend) drive visitor demand and can increase hotel occupancy and fares. Cultural events, theater openings, and football matches also contribute to higher local demand. New York/Newark area: September brings the start of many cultural seasons — Broadway previews, sports seasons (NFL/NBA preseason), and college football weekends — which can affect airport traffic at Newark Liberty International Airport (EWR). Travel impact: Expect price increases and busier transit links around major event dates; book flights and hotels early for September travel. CTA: Check event dates and book transport and accommodation early to avoid premium rates.

The best time to fly from Newark Liberty International Airport (EWR) to London Heathrow Airport (LHR) for a balance of price and weather is during shoulder seasons—September and late April. September offers milder temperatures in London and fewer tourists than July/August, often producing lower fares.
