Cheap flights from London to Cagliari

September is the cheapest month to fly this route, and the price calendar usually shows the drop starting right after the summer peak. July and August are the busiest and priciest weeks, when islanders abroad and British holidaymakers both head for the coast. Spring and autumn give you warm weather without the crowds, while winter fares stay low but the schedule thins out. Midweek departures — Tuesday and Wednesday especially — tend to undercut Friday and Sunday returns. Book well ahead for summer travel, and leave it later for autumn and winter, when seats are easier to find.

Ryanair, Easyjet, Vueling Airlines, Wizz Air UK and Wizz Air Malta are the low-cost names you will see on this route. BA EuroFlyer flies under the British Airways banner, while Austrian, Swiss and Air Baltic come in as connecting carriers through their own hubs. Mokulele Flight Service also appears in some searches. A low-cost ticket and a full-service one rarely cover the same things, so compare what each fare includes before you pick: a through-fare with one carrier can beat a cheaper seat once you add what you need. If you want to fly nonstop, filter for it — plenty of the low fares here involve a change of plane.

Cagliari Elmas is the airport for the city, and it sits close enough that the transfer into town is a short one rather than a trek. Trains and buses run between the terminal and the centre through the day, and taxis wait outside arrivals; late-night landings are the moment to check the timetable before you rely on public transport. Elmas is small and easy to walk through, so allow less time than you would at a big hub. If you are heading on to the beaches along the south coast or up into the island's interior, sort your onward transport before you land — the airport sits on the edge of the city, not in the middle of the resort strip.

• Read the baggage rules on the low-cost fares, where a cabin bag may be all that is included.
• If your trip is two separate tickets, leave a long gap in case the first leg runs late.
