Cheap flights from London to Boise

November is the cheapest month to fly from London to Boise. The fare calendar covers September through March and July, so you can compare prices across seasons. For a trip this long, expect to spend a full day travelling – midweek flights are often cheaper, but the calendar will show you the exact dates.

All airlines on this route – Air Canada, Delta Air Lines, KLM Royal Dutch Airlines, American Airlines, British Airways, Icelandair, Aer Lingus, United Airlines, Lufthansa City Airlines, and Helvetic Airways – operate connecting itineraries from London to Boise. None are low-cost, so you'll get full-service amenities, but baggage policies and included services vary. Compare connection times and check whether you need to re-check bags if your itinerary uses separate tickets.

Arriving in Boise, you'll touch down at Air Term Gowen Fld, the city's airport. It's a small field just south of downtown, so you can be in the centre within a short drive. Taxis, ride apps, and a couple of bus lines serve the terminal; there's no train. If you're arriving late, check the bus schedule – some routes end early. The airport itself is compact, so you'll get through quickly.
