Business class from Houston (IAH) to London (LHR) costs between $2,000 and $5,500 round-trip. British Airways and United Airlines compete on the route with an average flight time of 9.5 hours. The cheapest fares appear in January, February, March.
The transatlantic crossing from George Bush Intercontinental to Heathrow is one of those routes where the airline you choose shapes the experience almost as profoundly as the destination itself. United operates this corridor as a true flagship service, deploying its Polaris cabin on the nonstop — and if you haven't settled into a Polaris seat recently, the fully flat bed with its direct-aisle access has genuinely closed the gap with European carriers that once held a comfortable lead in long-haul comfort. British Airways counters with Club Suite on its newer A350 deliveries, offering that coveted door-to-close privacy that turns a nine-and-a-half-hour overnight into something resembling a proper night's sleep rather than an endurance event.
What makes IAH particularly interesting as a departure point is that it functions as a genuine hub rather than a spoke, meaning you're rarely dealing with the connection fatigue that plagues travelers routing through JFK or ORD to catch their transatlantic flight. Clear the international terminal at Bush, board directly, and you arrive into Heathrow Terminal 5 — which, for all the criticism Heathrow absorbs, remains one of the more gracefully designed arrival experiences in Europe, especially once you know to use the dedicated arrivals lounge access that comes with your business class ticket.
Timing matters considerably on this pairing. January through March offers the most compelling award availability and promotional fare windows, when leisure demand collapses after the holidays and corporate travel hasn't yet reached its spring intensity. October and November provide a secondary window with the added advantage of arriving in London during its most atmospheric season — overcast skies, early evenings, and a city that genuinely rewards the slower pace that follows a well-rested transatlantic crossing.
