Book cheap flights to Istanbul

Positioned as the singular bridge between two continents, Istanbul serves as a magnetic hub where the distinct cultures of Europe and Asia intersect across the Bosphorus. This ancient metropolis represents a vital junction for international travellers, offering a skyline defined by minarets and a deep-seated legacy of imperial influence.

The city’s architectural identity is best observed through the towering presence of the Hagia Sophia and the intricate tilework of the Blue Mosque. Wandering through the historic Sultanahmet district reveals layers of Byzantine and Ottoman history, while the Topkapi Palace provides a detailed glimpse into the opulent lives of former sultans. Near the waterfront, the Galata Tower stands as a medieval sentinel overlooking the bustling activity of the Golden Horn.

Visitors are often drawn to the sensory richness of the Grand Bazaar, where centuries of trade continue amidst a labyrinth of vaulted passages. The local atmosphere balances the solemnity of its ancient monuments with the energetic pace of modern Turkish life. Whether exploring the narrow alleys of Karaköy or observing the daily maritime traffic, the city remains a destination focused on historical discovery and cultural depth.

High season highlights

The peak period in Istanbul typically spans from April to June and from September to October, when the city enjoys a temperate Mediterranean climate. During these months, temperatures generally hover between 18°C and 27°C, creating a lively atmosphere where the streets of Sultanahmet and the Bosphorus shoreline are bustling with activity. Travellers arriving at Istanbul Airport or Sabiha Gökçen International Airport during this window are greeted by clear skies and a city in full bloom, particularly during the Istanbul Tulip Festival.

Life during the high season shifts outdoors, with rooftop terraces and waterfront promenades becoming the social heart of the metropolis. The longer daylight hours, often providing up to 12 hours of sun, allow for extensive exploration of open-air landmarks and lively evening markets. While the pace is energetic and popular sites see higher foot traffic, the consistent warmth and moderate temperatures make it the most comfortable time for walking tours. Cultural calendars are packed with international arts festivals, reflecting the city’s status as a global bridge between continents.

Low season characteristics

The low season arrives with the cooler, damp months of December to February, when temperatures often fluctuate between 3°C and 9°C. During this time, the city takes on a more contemplative and cinematic quality, occasionally dusted by snow that transforms the domes of the Hagia Sophia and Blue Mosque into a white landscape. Visitors landing in the winter will find a much quieter version of the city, where the brisk wind off the Sea of Marmara encourages retreat into the historic coffee houses and grand covered bazaars.

Social life moves indoors, centred around the warmth of traditional tea gardens and steamy hammams that have operated for centuries. While rain is more frequent, the absence of large crowds offers a more intimate connection with the city’s vast museum collections and architectural wonders. The shorter days are compensated for by the glow of street lamps reflecting off wet cobblestones, creating a moody, atmospheric environment that is distinct from the summer glare. This season provides a peaceful perspective on Istanbul, ideal for those who prefer cultural depth over sunny spectacles.

Two major international gateways serve as the primary arrival points for travellers, positioned on either side of the continental divide that defines the city. Whether your flight to Istanbul touches down on the European or Asian side, you will find extensive infrastructure designed to bridge the distance between the tarmac and the historic centre.

Istanbul Airport (IST)

Istanbul Airport, identified by the IATA code IST, is the primary international hub for the region and is located approximately 35 km north-west of the city centre in the Arnavutköy district. As the main base for Turkish Airlines, this facility operates as one of the largest and most modern aviation hubs in the world, handling a vast network of global and domestic flights to Istanbul through its massive single-terminal structure. The airport serves as a critical link between Europe, Asia, and Africa, offering extensive amenities for long-haul transit passengers and those ending their journey in the city.

From the arrivals hall, the quickest link into the city is the M11 Metro line, which connects the airport to Kağıthane and Gayrettepe in roughly 30–40 minutes. From these stations, passengers can transfer to the M2 line to reach Taksim Square or Şişli. Alternatively, the Havaist airport shuttle buses provide direct, comfortable transport to major hubs such as Beşiktaş, Aksaray, and Kadıköy, with journey times ranging from 60 to 90 minutes depending on traffic conditions. Taxis wait around the clock at the ranks just beyond the arrivals exit, offering a direct route to hotels in the Sultanahmet or Beyoğlu districts.

Sabiha Gökçen International Airport (SAW)

Located on the Asian side of the city, Sabiha Gökçen International Airport (SAW) sits about 40 km south-east of the central districts in the Pendik area. This airport functions as a major base for low-cost carriers, including Pegasus Airlines and AJet, focusing heavily on point-to-point European routes and frequent domestic connections across Turkey. Despite having a smaller footprint than its counterpart on the European side, it features a modern terminal capable of handling high passenger volumes with efficiency.

Travellers landing here can utilise the M4 Metro line, which provides a direct rail link from the airport to Kadıköy, the lively cultural heart of the Asian side, in approximately 50 minutes. For those staying on the European side, the Havabüs shuttle service runs frequently to Taksim Square, typically taking between 60 and 90 minutes to complete the trip. Another practical option is to take the metro to Ayrılık Çeşmesi and transfer to the Marmaray commuter rail, which runs under the Bosphorus to reach Sirkeci and Yenikapı in the historic peninsula. Official taxis and ride-hailing services are also readily accessible at the arrivals level for door-to-door transit.

From Byzantine domes to spice-scented bazaars, Istanbul rewards curious travellers at every turn.

• Hagia Sophia: Originally a Byzantine cathedral and later an Ottoman mosque, this architectural marvel represents the shifting soul of the city through its massive dome and intricate gold mosaics.
• Topkapi Palace: The former residence of sultans offers a glimpse into imperial life, featuring lush courtyards and a treasury that houses some of the most famous gemstones in the world.

• Galata Tower: Standing tall since the 14th century, this stone watchtower provides a panoramic vantage point where you can watch the ferries criss-cross the water as the sun sets.
• Basilica Cistern: This subterranean reservoir, supported by 336 marble columns, offers a cool, atmospheric escape where the sound of dripping water creates a hauntingly beautiful rhythm beneath the city streets.
• Bosphorus Strait: A boat trip along this natural waterway allows you to see the city from the water, passing grand waterfront mansions and fortresses that bridge the gap between Europe and Asia.
