How JFK–LHR gets cheaper
- Regional point-of-sale pricing: the same flight is often filed at different tariffs in different countries and currencies. How it works.
- Split-hub routing: pricing JFK to a competitive hub and that hub to LHR as separate tickets can undercut the nonstop, with the risk that separate tickets are not protected if you miss the connection.
- Timing: Airline revenue management systems tend to release unsold corporate hold blocks back into discounted K, L, and V buckets at roughly 60, 45, and 21 days prior to departure.
- Nearby airports: departing from EWR (Newark Liberty), LGA (New York LaGuardia), or arriving at LGW (London Gatwick), STN (London Stansted), LTN (London Luton), can change the fare.
