Cheap flights from London to Sofia

November is the cheapest month on this route, and the shoulder weeks around it, late autumn and early spring, tend to be gentler on fares than the summer peak. July and August are the busiest, when both London and Sofia empty out on holiday, and the December holidays push prices up again. Weekday departures are usually lighter than Friday and Sunday flights, so compare a Tuesday against a Sunday before you commit. Bulgarian public holidays and UK school half-terms are worth checking, because they lift demand at both ends of the route. Book a few weeks ahead in winter and earlier for summer.

Low-cost carriers do most of the work on this route. Ryanair, Wizz Air and its UK and Malta arms, Easyjet, Jet2 and Vueling all sell tickets between London and Sofia, and on those fares a small cabin bag is normally included while a checked bag or a chosen seat costs extra. British Airways is the full-service option, with a more generous baggage allowance and a higher fare to match. Some carriers sell this as a direct flight and others as a connection, so read the itinerary before you compare prices, because a change of plane on separate tickets is a different product from a single booking.

Sofia Airport is the only airport on the Bulgarian side of this route, so every flight lands in the same place. It sits a short ride from the centre of the capital, with taxis, buses and the metro covering the trip into town. The terminal is compact and easy to cross, but queues at passport control can build when several flights land together. If your flight arrives late, check the last connections into the city before you commit, and keep your onward address handy for the taxi rank.

Country facts: Wikidata

• Check which London airport your fare leaves from, because the city has several and they are not interchangeable.
• Confirm what the low-cost fare includes: a cabin bag is usually in, a checked bag and seat choice usually are not.
• If your itinerary changes planes, make sure both legs sit on one ticket so a delay is covered.
• Check the entry rules for Bulgaria against your passport before you pay.
• Compare your dates against the price calendar, since November is the cheapest month on this route.
• Book the return leg early if you are travelling over the winter holidays, when seats fill up.
