Cheap flights from London to Kauai Island

March is the cheapest month on this route, so aim for it if your dates are flexible. Fares are tracked across September, October, November, December, February, March and June, and those are the months to watch on the price calendar. Autumn and early winter sit outside the holiday peaks, while June and December fall right inside them and cost more. Midweek departures usually come in below weekend ones, and it pays to avoid the days either side of a school break.

There is no low-cost carrier in the mix, so you are comparing full-service airlines rather than stripped-back fares. British Airways, Virgin Atlantic, Delta Air Lines and Icelandair appear alongside KLM Royal Dutch Airlines, Air France, Swiss, Lufthansa, Lufthansa City Airlines and Air Dolomiti. Because nothing on this route is nonstop, the carrier you pick decides where you break the journey and how long the layover runs. Baggage and seat rules differ by airline and by fare type, so read what your ticket includes before you pay.

Your flight lands at Lihue, the airport that serves Kauai. It is the arrival point for the whole island, and it sits near the town of Lihue, with everywhere else reached by road. Rental cars are the usual way in, and the desks get busy when flights land close together, so reserving ahead saves time. Shuttles and taxis cover the nearer places. Think about the hour you land too: after a long trip with a connection behind you, driving in the dark is the last thing you want.

Country facts: Wikidata

• Check which London airport your fare leaves from, since London City, Gatwick, Heathrow, Luton and Stansted all appear and the choice changes your total travel time.
• Make sure both legs sit on one ticket, or leave a generous gap if you are booking the connection separately.
• Read the baggage allowance on your fare, because a light ticket may not include a checked bag.
• Sort your passport and US entry paperwork before you book, not after.
• Look at the price calendar first, since March is the cheapest month in the data.
• If you are flying in June or December, book earlier than you would in the quieter months.
