Why this route has hidden savings

Heathrow majors, Gatwick low-cost long-haul, and one-stop US-domestic combinations all serve the same city pair at very different price points. Most search engines default to LHR ↔ LAX direct and never test the alternatives.

Airport options on both ends
London has 2 viable origin airports (LHR, LGW). Los Angeles has 4 arrival airports (LAX, BUR, SNA, LGB). Each pairing has its own fare distribution — most search engines never test more than one.
Stopover hubs that beat direct
One-stop routings via New York (open-jaw), Reykjavík, Dallas (AA) regularly undercut the direct fare on this corridor — and some carriers throw in a free multi-day stopover as part of the ticket.
Date flexibility you're not using
Shifting departure by even one weekday inside a ±3-day window frequently flips fare class on this route. The cheapest months historically are January, February, October, but fares still swing 30%+ week-to-week within those months.
