Cheap flights from London to Mostar

Summer around Mostar brings long, hot days and evenings that stay light, while winter is cooler with the daylight cut short — and fares follow that rhythm. January is the low point for tickets on this pairing. The fare calendar here covers October through February, then June and July, so you can set the seasons side by side before you commit. Christmas and the school holidays in the UK are the dates worth booking early for.

Connections come first on this route: with no nonstop service, every ticket from the ten listed carriers involves a change of plane, and where that happens depends on the airline. Eurowings and Air Baltic run on a low-cost model, so the base fare buys your seat and bags are added separately. KLM Royal Dutch Airlines, LOT Polish Airlines, Lufthansa, Lufthansa City Airlines, Croatia Airlines, Air Dolomiti, Edelweiss Air and Helvetic Airways operate full service, where a cabin bag comes with the ticket and checked baggage is typically included too. Price the whole trip with luggage, not just the headline fare, and the ranking between them can change.

A landing time matters more than usual on this route. With every itinerary connecting somewhere, the fare you pick decides when you actually reach Mostar, and an evening arrival changes the practical picture: the way into town needs sorting before you fly, and your first evening shrinks to the essentials. Mostar has a single airport under its own name, so there is no second airfield to weigh — the detail to verify is the scheduled arrival time and how it fits the rest of that day. If you are travelling on elsewhere in Bosnia and Herzegovina, leave slack between the landing and your onward plan.

Country facts: Wikidata

• Check whether your connection is on a single through-ticket or two separate bookings, and leave generous slack if it is the latter.
• Add baggage costs before you compare, because Eurowings and Air Baltic sell checked bags separately while the full-service carriers include more.
• Compare departure airports as well as fares, since the one you pick changes the connection you get.
• Check the entry documents Bosnia and Herzegovina requires, plus any transit rules that apply on your connecting leg.
• Scan the calendar across October to February and then June and July rather than a single date, and note that January comes in lowest.
