When to fly

Traveling outside peak summer crowds usually means better availability across all carriers. March stands out as the cheapest month on this route when demand settles after winter holidays but before Easter travel picks up. Consider shoulder periods in April or October where fares tend to soften without sacrificing decent daylight hours. Booking well ahead works for most airlines, though last-minute seats occasionally appear if you are willing to trade comfort for savings.

Airlines and what to expect

Many carriers route passengers differently depending on their network structure and hub locations. Jet2 and TUI Airways typically fly direct from Kos Ippokratis to London Gatwick or Stansted during tourist seasons. Ryanair and Easyjet operate budget services, sometimes connecting through secondary airports rather than flying nonstop. British Airways and its subsidiary BA EuroFlyer generally land at Heathrow with full-service baggage allowances included in base fares. Condor, Aegean Airlines, Edelweiss Air, and Hahn Air Systems offer alternative paths that may involve one stop or seasonal schedules.

Arriving — London

London has five major airports spread across the city so planning your ground transport matters before you land. Heathrow sits far west with excellent rail links but longer commute times to central zones. Gatwick and Stansted lie south and northeast respectively, each with express train options though frequency varies by time of day. Luton is north of the capital while London City Airport serves business travellers near Canary Wharf with a Docklands Light Railway connection. Factor in extra travel time when choosing your arrival airport rather than picking solely on fare price.
