Cheap flights from London to Graz

The cheapest month on this route is December, so start there if your dates are flexible. Fares are listed from September through July, which means August is the gap in the calendar — if you have to travel then, book early and compare what is on offer. Spring and autumn sit in the middle, with more dates to choose from and less pressure on seats. Check midweek departures against Friday and Sunday ones, and watch the weeks around school holidays in both countries, when fares climb and the good connections go first.

The route mixes low-cost and full-service carriers. Easyjet, Eurowings and Pegasus sell the bare ticket and charge for what you add, so a checked bag and a seat choice can change the total. BA EuroFlyer, Swiss, Lufthansa, Lufthansa City Airlines, Air Dolomiti, Edelweiss Air and Helvetic Airways are the full-service names, where a bag and a snack usually come with the fare. Some of these fly you to Graz non-stop; others put you on a connection through their own hub, which adds time but can open up cheaper days. Read the fare rules before you compare totals, because a low headline fare with a bag added is not always the cheaper ticket.

Graz has one airport, so there is no second gateway to choose between — you land at Graz Airport, which sits outside the city rather than in the middle of it. Buses and taxis cover the run in, and the transfer is straightforward. On the way home, check which London airport your ticket names: London City, Gatwick, Heathrow, Luton and Stansted are all options, and they are not interchangeable. If you fly with a connection, ask at the desk whether your bag is checked through to Graz.

Country facts: Wikidata

• Which London airport you leave from — London City, Gatwick, Heathrow, Luton and Stansted are all options, and the closest one to you is not always the one with the fare you want.
• What your low-cost fare includes, since Easyjet, Eurowings and Pegasus charge extra for a checked bag and a chosen seat.
• Whether a connection is on one ticket or two, because separate tickets leave you carrying the risk of a missed onward flight.
• That your passport and any entry documents are valid for Austria for the whole trip.
• Whether your dates fall in December, the cheapest month here, or in August, which the price calendar does not cover.
