January and February consistently offer the cheapest fares to London, with East Coast roundtrips often under $350. November is also very affordable. Avoid June–August and December holidays for the best prices.
Heathrow (LHR) has the most flights but can be priciest. Gatwick (LGW) hosts budget carriers with cheaper fares. Both have excellent Tube/train connections to central London in 30–60 minutes.
Book 1–4 months ahead for the best economy fares. The NYC–London route has so much competition that last-minute deals also appear regularly. Set up alerts to catch fare drops.
