London (LHR) to New York JFK (JFK) flights

London Heathrow to New York JFK is the most-flown transatlantic in the world: 122 weekly nonstops, 17 daily departures from 07:25 through 20:05, six carriers competing on the same 5,540 km corridor. British Airways and American Airlines (joint-venture partners) operate the densest schedule from LHR Terminal 5; Virgin Atlantic and Delta (also joint-venture partners) cluster at Terminal 3; JetBlue and Aer Lingus round out the field from T2.

Block time is about 8 hours westbound — the prevailing jet stream adds an hour versus the eastbound return at roughly 7 hours. Late-morning LHR departures land JFK in the mid-afternoon local time, leaving a full New York evening intact; the alternative is a 19:00–20:00 LHR push landing JFK around 22:00, useful when you want to sleep on board and start fresh the next day.

This is the route to use loyalty status on: every major airline lounges at LHR — Concorde Room (BA), Clubhouse (VS), Polaris (UA via codeshare), Admirals Club (AA) — sit right next to each other on Terminal 5 and Terminal 3 airside.
