Cheap flights from London to Denpasar Bali

October is the cheapest month on this route, and the price calendar shows how the other months compare. Fares rise around UK school holidays and the end-of-year break, when London departures and Bali beds both fill up, so if your dates fall there, book well ahead. Midweek departures tend to cost less than Friday and weekend ones. Outside those peaks the gap between months is modest, so it pays to check a few dates rather than fix on one. Because every option connects, shifting your date by a day can also change which hub you pass through.

Every flight on this route connects, so the airline you pick decides where you change and how long you wait. Qatar Airways and Etihad Airways route you through the Gulf, Finnair, Swiss and Lufthansa through Europe, and China Eastern Airlines, China Southern Airlines and Indigo through Asia. Aer Lingus turns up on some itineraries as a short first leg rather than the carrier that takes you all the way. Indigo and AirAsia X are low-cost: the ticket buys a seat, and bags and food are add-ons. On full-service carriers a checked bag and meals usually come with the fare, but the lightest fare on the same airline often drops them, so read the fare rules before you pay.

Ngurah Rai is the airport you land at, on the narrow strip of land south of Denpasar. It sits close to Kuta, Legian and Seminyak, so those beach towns are a short ride away, while Ubud and the north of the island take much longer, especially in traffic. Official airport taxis, ride-hailing apps and hotel transfers all work, but app pickups usually happen at a designated point rather than at the kerb outside arrivals. Immigration can be slow when several long-haul flights land together, so keep your onward address and travel documents to hand. If you land late at night, arrange your transfer before you fly rather than sorting it out on the spot.

Country facts: Wikidata

• Check which London airport your ticket actually uses, because Heathrow, Gatwick, Stansted, Luton and London City are far apart.
• Look at the baggage allowance on any low-cost leg with Indigo or AirAsia X, where a checked bag costs extra.
• Confirm whether your connection is on one ticket or two, since a missed self-transfer is not covered the way a single ticket is.
• Check your passport validity and the entry rules for Indonesia before you book, not the week you fly.
• Book early if you are travelling over the end-of-year break, and compare October against your own dates.
• Compare total journey time, not just the fare, because a cheap connection can add a long layover.
