When to fly

May is the cheapest month here, and it sits in the gap between the Caribbean winter high season and the summer school holidays. The price calendar runs from October through August, and fares climb through the European winter and around Christmas. If your dates are tied to school breaks or the festive weeks, book early; if they can move, compare the weeks either side of May first.

Airlines and what to expect

British Airways and Virgin Atlantic are the two UK carriers on the list, and since this route has direct flights, they are where to start looking for a nonstop from London to Hewanorra. Air Canada, WestJet and American Airlines usually come up as one-stop itineraries across their North American networks, while Aer Lingus, Icelandair, Helvetic Airways, Lufthansa City Airlines and Lufthansa connect within Europe. What the fare includes differs more than the timetable does, so weigh checked bags, seat selection and meals into the total before you pick.

Arriving — St Lucia

If your flight lands at Hewanorra late in the day, sort the onward transfer before you fly: the airport sits in the south of the island, and the drive up to Castries and the main resorts is a long one on winding roads. Taxis and shared shuttles meet incoming flights, and hire cars are available at the terminal, but the choice thins out after dark. If you are staying in the north, a daytime arrival, even with a connection, may suit you more than a later nonstop.

Check before you book

  • Check whether the itinerary is a single ticket or two separate ones — with separate tickets, a missed connection is yours to rebook.
  • Compare door-to-door journey time as well as fare, since a one-stop option can take several hours longer than a nonstop.
  • Check which London airport you fly from — City, Gatwick, Heathrow, Luton and Stansted sit far apart and serve different carriers.
  • Check what the fare covers before you pay: checked baggage, seat selection and meals are extras on some tickets.
  • Check passport validity and entry rules for Saint Lucia for everyone on the booking.
  • Check the calendar around your dates, since May prices lowest and fares climb over Christmas and the European winter.
