Flights from the UK and Ireland
You can fly direct from the UK to Istanbul (Istanbul or Sabiha Gökçen airports), İzmir, Bodrum, Dalaman and Antalya. Reaching any other destination in Turkey involves a change in Istanbul.
Direct, scheduled flights are provided by Turkish Airlines (THY; http://turkishairlines.com). THY flies from London (Gatwick or Heathrow), Birmingham, Manchester and Edinburgh. British Airways (BA; http://britishairways.com) links London (Gatwick or Heathrow) with Istanbul (Istanbul or Sabiha Gökçen) year-round, with less frequent flights from, Manchester, Birmingham and Edinburgh. London is generally the cheapest departure airport.
Budget and charter flights
Among budget airlines, easyJet (http://easyjet.com) offers summer flights from Gatwick to İzmir; from Gatwick, Luton and Manchester to Antalya; from Bristol, Edinburgh, Liverpool, Luton, Gatwick or Stansted to Bodrum; and from Bristol, Gatwick, Manchester, Edinburgh or Stansted to Dalaman. Advance low-season fares can be very cheap, though late bookings can cost a premium.
Pegasus (http://flypgs.com) links Heathrow and Stansted to Istanbul’s Sabiha Gökçen International Airport year-round, from where they have a far-reaching network of domestic flights . Jet2 (http://jet2.com) has summer-only flights to Antalya, Dalaman and Bodrum from Glasgow, Edinburgh, Leeds–Bradford, Manchester, the East Midlands and Newcastle.
The widest choice of charter flights to Turkish coastal resorts is offered by TUI (http://tui.co.uk), who filled the void created by the collapse of Thomas Cook in 2019; they also took over Thomson Holidays. There are year-round charters to Antalya and Dalaman, while services to İzmir and Bodrum usually operate from late April or early May to late October. Peak-season prices can be as high as scheduled flights, but in winter they be very low.
Flights from Ireland
From Belfast, British Airways offer year-round daily scheduled services, involving a stop in London or Manchester, but prices are relatively high compared to other UK airports. From Dublin, Turkish Airlines have a direct daily flight to Istanbul Airport. Usually the cheapest option is to use a budget carrier from either Dublin or Belfast to one of the UK cities, and connect with easyJet or Pegasus to Turkey from there.
