Los Angeles to London is a straight shot of about ten hours eastbound, and the cheapest seat we see today is $328. British Airways, Virgin Atlantic, American and United all run the route, and the overnight timing means you leave in the evening and arrive mid-afternoon the next day.
January through March is the cheapest stretch, once the New Year rush clears. Summer and the Christmas fortnight are the peaks to avoid. Most flights land at Heathrow, which has fast rail links into central London, so you do not lose the time you saved on a cheap fare sitting in traffic.
London is also the easiest gateway to the rest of Europe from the West Coast. Paris is two hours twenty on the Eurostar once you arrive, which makes a two-city trip simple to plan. The London city guide has the practical detail; Paris is the obvious add-on.
