Cheap flights from London to Kos

October is the cheapest month to fly from London to Kos, and it is the one to aim for if your dates can move. Summer costs more, above all around UK school holidays, when families fill the direct flights and fares climb. Midweek departures usually undercut weekend ones, so shifting your trip by a day can change the price. Book well ahead for July and August; for October you can often leave it later, though the island grows quieter as the season ends. Outside the summer months, expect connections rather than direct flights.

Ryanair, Easyjet, Wizz Air UK and Jet2 are the low-cost names here, and they are the ones that usually fly you straight to Kos in season. BA EuroFlyer covers the route from the British side, while Aegean Airlines and Sky Express connect through Greece. Austrian, Brussels Airlines and Edelweiss Air sell one-stop itineraries through their own hubs. The difference that matters is what is included: low-cost fares are seat-only, with cabin and hold bags charged on top, while full-service tickets tend to bundle a bag and a meal. Compare the total, not the headline fare.

Ippokratis is the only airport on Kos, so every flight from London lands in the same place, whatever you paid for the ticket. It sits outside Kos Town, a road transfer rather than a walk, with the main resorts spread along the coast beyond it. Taxis and shuttle coaches meet the seasonal arrivals, and rental desks are on site if you would rather drive yourself. In summer the terminal gets busy when several flights land close together, so allow time for bags. Sort out your transfer before you fly, especially on a late arrival.

Country facts: Wikidata

• Decide which London airport suits you, since the city has more than one and the choice shapes your whole journey.
• Check what the low-cost fare includes, because cabin and hold baggage are charged separately on this route.
• If your connection is booked on separate tickets, leave a generous gap so a delay does not cost you the onward flight.
• Confirm your passport and entry documents for Greece are valid for your travel dates.
• Book early for summer and school-holiday dates, and keep October in mind if your plans are flexible.
