Cheap flights to Indonesia

Flights from the UK to Indonesia take approximately 13–16 hours with at least one connecting stop. There are no non-stop direct services from the UK. Common routes go via Dubai, Doha, Singapore, Kuala Lumpur, or Hong Kong. Singapore is a particularly efficient hub for Indonesia connections, with short onward flights to Bali, Jakarta, and other Indonesian cities.

The best time to visit Indonesia varies significantly by island due to the archipelago's vast geographic spread. Bali and Lombok are best during the dry season from May to September — June, July, and August are peak months with clear skies and calm seas. April, May, and October are excellent shoulder months. The wet season (November–March) brings heavy rain, particularly in afternoons, and can affect some activities. Komodo is best April–August. For Borneo (wildlife and orangutans), the dry season (April–October) is preferred. The Gili Islands mirror Bali's weather patterns.

Indonesia has several international airports. The primary gateways are Ngurah Rai International Airport (DPS) in Bali — the most popular tourist gateway — and Soekarno-Hatta International Airport (CGK) in Jakarta, the capital and busiest airport. Other international airports include Juanda International (SUB) in Surabaya, Lombok International (LOP), Sultan Hasanuddin (UPG) in Makassar, and Frans Kaisiepo Airport (BIK) in Papua. Garuda Indonesia, Lion Air, and other Indonesian carriers provide extensive domestic connections throughout the 17,000-island archipelago.

The cheapest time to fly to Indonesia from the UK is during the wet season — particularly January through March. Bali's wet season brings afternoon rain but many sunny mornings, and prices drop considerably compared to the peak dry season. November is also relatively affordable before the Christmas surge. For budget travellers willing to tolerate some rain, the wet season offers excellent value across Indonesia.

Indonesia spans two main time zones relevant to most tourists. Western Indonesia Time (WIB, UTC+7) covers Jakarta, Sumatra, and Java — 7 hours ahead of the UK (GMT), 6 hours in BST. Central Indonesia Time (WITA, UTC+8) covers Bali, Lombok, and Komodo — 8 hours ahead of the UK (GMT), 7 hours in BST. Eastern Indonesia Time (WIT, UTC+9) covers Papua and Maluku. Indonesia does not observe Daylight Saving Time.

Indonesian (Bahasa Indonesia) is the official national language and serves as the lingua franca across the archipelago's hundreds of ethnic groups, each with their own language. Bahasa Indonesia is relatively straightforward in structure and pronunciation. English is widely spoken in Bali's tourist areas, hotels, restaurants, and tour operations — Bali is one of Southeast Asia's most English-friendly tourist destinations. In Jakarta and other major cities, English is common in business and hospitality. On more remote islands and in rural areas, Bahasa Indonesia (or a local dialect) is the primary language.

UK driving licence holders are not formally permitted to drive in Indonesia on a UK licence alone — an International Driving Permit (IDP) is required. Indonesia drives on the left. In Bali, motorbikes and scooters are a popular and practical way to get around, though many tourists ride without the correct licence — this is technically illegal and may void travel insurance. If you choose to ride a scooter, wear a helmet at all times and exercise extreme caution. Car hire with a driver is very affordable in Bali and is a recommended alternative for visiting temples, rice terraces, and other sights.

There are no non-stop direct flights from the UK to Indonesia. All routes require at least one connecting stop. The most popular connections for UK passengers are via Singapore (Singapore Airlines — widely recommended), Dubai (Emirates), Doha (Qatar Airways), Kuala Lumpur (Malaysia Airlines), and Hong Kong (Cathay Pacific). The Singapore connection is particularly efficient — Singapore Changi Airport is one of the world's best transit airports, and onward flights to Bali, Jakarta, and other Indonesian cities are frequent and short (90 minutes to Bali).

Airlines serving the UK–Indonesia route include Emirates (via Dubai), Qatar Airways (via Doha), Singapore Airlines (via Singapore), Garuda Indonesia (the national carrier, connecting via Singapore or other hubs), Malaysia Airlines (via Kuala Lumpur), Cathay Pacific (via Hong Kong), and Etihad (via Abu Dhabi). Singapore Airlines via Singapore is widely regarded as one of the best options for both service quality and efficient connection times.

British passport holders can visit Indonesia visa-free for up to 30 days at major entry points, including Bali's Ngurah Rai Airport and Jakarta's Soekarno-Hatta Airport. For stays of 31–60 days, a Visa on Arrival (VoA) costing IDR 500,000 (approximately £25) is available at major international airports and is extendable for a further 30 days at immigration offices in Indonesia. An e-Visa option is also available. Ensure your UK passport has at least 6 months' validity and that you have a return or onward ticket.

Return flights from the UK to Bali (the most popular destination) typically cost between £550 and £1,300 depending on the airline, routing, and travel period. Jakarta may be slightly cheaper as a major hub. Singapore Airlines via Singapore and Qatar Airways via Doha are frequently among the best-value options. July–August (Bali high season) and Christmas/New Year are the most expensive periods. Booking 3–5 months in advance for peak season delivers the best combination of price and availability.

Indonesia offers extraordinary diversity across its 17,000+ islands. Highlights include Bali (temples, rice terraces, surf beaches, yoga retreats, and vibrant nightlife in Seminyak and Kuta, balanced with the spiritual calm of Ubud), Komodo Island (the last wild habitat of Komodo dragons, plus world-class diving), the Gili Islands (car-free white-sand island paradise near Lombok), trekking on the volcanic Mount Rinjani in Lombok or Mount Bromo in Java, the UNESCO-listed Borobudur (the world's largest Buddhist temple complex in central Java), orangutan encounters in Borneo's Tanjung Puting National Park, surfing legendary breaks in the Mentawai Islands and G-Land, and the traditional culture of the Toraja people in Sulawesi.

The currency in Indonesia is the Indonesian Rupiah (IDR). Cash is widely used — particularly in markets, local warungs (restaurants), transport, smaller shops, and less touristy areas. Credit cards (Visa and Mastercard) are accepted in hotels, larger restaurants, resorts, and tourist businesses in Bali and Jakarta. ATMs are plentiful in tourist areas but can be limited in more remote locations. The Rupiah has many zeros — take care when handling cash. Bali and Lombok are extremely good value for British travellers at current exchange rates.

Travel insurance is strongly recommended for Indonesia. Medical facilities in Bali's tourist areas have improved but remain limited for serious conditions — severe cases may require evacuation to Singapore or Australia, which is extremely costly without insurance. Outside major tourist areas and cities, facilities are very basic. Health risks include dengue fever (mosquito repellent is essential), bali belly (food and water hygiene), and rabies (avoid contact with monkeys and stray animals in Bali). Your policy should cover medical expenses, emergency evacuation, diving-related incidents if applicable, trip cancellation, and loss of belongings.

Standard economy baggage allowances for flights to Indonesia from the UK vary by carrier. Singapore Airlines typically allows 25–30kg checked plus 7kg carry-on. Emirates and Qatar Airways allow 23–30kg. Garuda Indonesia international routes typically allow 30kg in economy. Domestic flights within Indonesia on Garuda, Lion Air, Citilink, or Batik Air often include 15–20kg on economy fares — always verify domestic allowances as they vary considerably by airline and fare type.

Indonesia has a tropical climate characterised by high temperatures and humidity year-round, with a distinct wet and dry season in most regions. Bali and most of Java have a wet season from November to March (afternoon thunderstorms, heavy rain, 27–31°C) and a dry season from April to October (sunny, lower humidity, 26–30°C). Jakarta is similar but hotter and more polluted year-round. Sumatra has a more complex pattern with two wet seasons. Papua is wet and humid throughout the year. Sea temperatures around Indonesia are consistently warm at 27–30°C. Altitude in Java and other volcanic islands creates cooler microclimates — mornings on Mount Bromo or Mount Rinjani can be surprisingly cold.
