Book Flights to Istanbul, Turkey
Istanbul — the city where Europe meets Asia, the Bosphorus meets three seas, and 3,000 years of history layer atop each other — is one of the world's most extraordinary and unmissable destinations. As the capital of the Byzantine Empire (Constantinople) for over 1,000 years and the Ottoman Empire for nearly 500 years, Istanbul's historic core (Sultanahmet) contains a density of world-class monuments — Hagia Sophia, Topkapi Palace, the Blue Mosque, the Basilica Cistern — unmatched in any city of comparable size. At the same time, Istanbul Airport (IST) is one of the world's largest aviation hubs, served by Turkish Airlines to more countries than any other airline, making Istanbul a uniquely accessible global city from virtually any origin.
Istanbul Airport (IST) is served by Turkish Airlines (global hub, nonstop from New York, LA, and Chicago), British Airways (London LHR), Lufthansa (Frankfurt, Munich), Air France (Paris CDG), KLM (Amsterdam), and Emirates (Dubai).

Why Visit Istanbul, Turkey?
Istanbul combines Hagia Sophia, Topkapi Palace, the Grand Bazaar, the Bosphorus Strait, Ottoman culinary culture, and one of the world's greatest aviation hubs — all in a city of extraordinary historical depth, extraordinary value, and extraordinary energy.
Hagia Sophia
The World's Greatest Building — 1,500 Years of HistoryHagia Sophia (Ayasofya) — built by Emperor Justinian I between 532 and 537 AD and serving as the world's largest cathedral for nearly 1,000 years, then as the Ottoman Empire's principal mosque from 1453 to 1934, then as a secular museum until 2020 (when it was reconverted to a mosque) — is arguably the most historically significant building in the world. The 31-metre dome — an engineering marvel that appeared to float, unsupported, above the nave — revolutionised architecture across the Christian and Islamic world. The Byzantine mosaics (partially visible during non-prayer hours), the 4th-century Egyptian obelisk in the adjacent Hippodrome, and the overwhelming interior space together constitute one of the defining experiences in world travel.
The Dome That Changed Architecture
Hagia Sophia's dome (31 metres in diameter, 55 metres above the floor) — suspended on four pendentives at the corners rather than a solid drum — was the most technically advanced dome structure in the world for a thousand years. Its influence on Islamic architecture (the Blue Mosque directly opposite was built to rival it) and on Renaissance dome design (Brunelleschi's Florence, Michelangelo's St. Peter's) makes Hagia Sophia the mother of all domed architecture
Topkapi Palace
The Ottoman Empire's Imperial Heart — 400 Years of Sultanic PowerTopkapi Palace — the primary residence of the Ottoman sultans from 1465 to 1853, commanding the promontory where the Bosphorus meets the Golden Horn and the Sea of Marmara — is the world's most extensive surviving imperial palace complex: 700,000 m² of pavilions, courtyards, gardens, and treasury chambers that housed up to 10,000 residents at its height. The Harem (700 rooms), the Imperial Treasury (containing the 86-carat Spoonmaker's Diamond, the Topkapi Dagger, and the arm bone of John the Baptist), the Sacred Relics rooms, and the panoramic Fourth Courtyard are the essential highlights.
The Spoonmaker's Diamond
The Spoonmaker's Diamond (Kaşıkçı Elması) — an 86-carat pear-shaped diamond of extraordinary clarity, now displayed in Topkapi's Imperial Treasury — is Turkey's most famous jewel and one of the world's largest cut diamonds. According to legend, it was found in a rubbish heap by a poor spoonmaker who sold it for three wooden spoons. It was acquired by the Ottoman court in 1774 and has been at Topkapi since
Grand Bazaar and Spice Bazaar
The World's Oldest and Largest Covered MarketsThe Grand Bazaar (Kapalıçarşı) — established in 1455 immediately after the Ottoman conquest of Constantinople — is the world's oldest and largest covered market: 61 covered streets, over 4,000 shops, and up to 400,000 visitors per day. Gold jewellery, Turkish carpets, ceramics, textiles, leather, and spices fill its labyrinthine corridors. The adjacent Spice Bazaar (Mısır Çarşısı, 1664) — a smaller, L-shaped market at the Golden Horn waterfront — specialises in spices, dried fruits, Turkish delight, and traditional medicinal herbs.
Turkish Carpet Buying
Istanbul's Grand Bazaar is the world's most important centre for Turkish carpet trading — hand-knotted Anatolian, Caucasian, and Persian carpets ranging from small kilims (flat-weave rugs, from €50) to large hand-knotted silk carpets (€5,000+). Understanding the difference between hand-knotted (ipek/yün), machine-made, and kilim weaves before visiting prevents the most common tourist purchases that disappoint. Several honest dealers offer fixed prices
Bosphorus Strait
The Waterway That Divides Two Continents — Europe and AsiaThe Bosphorus Strait — 31 km long, 700 metres at its narrowest, separating the European and Asian sides of Istanbul — is one of the world's most strategically and scenically significant waterways. Istanbul is the only city in the world built on two continents; the Bosphorus is crossed by three suspension bridges (including the 15 July Martyrs Bridge / former Bosphorus Bridge, 1973) and the Marmaray undersea rail tunnel (2013). The 2-hour public ferry from Eminönü to Anadolu Kavağı up the strait is one of the world's great urban boat journeys: past Ottoman yalıs (waterfront mansions), fortresses, and the two suspension bridges.
The Bosphorus Ferry Experience
The Şehir Hatları public ferry from Eminönü (Golden Horn waterfront) to Anadolu Kavağı (a fishing village at the Black Sea entrance) — running twice daily and taking approximately 1.5 hours each way — is arguably the world's finest urban ferry journey: passing the Dolmabahçe Palace, the Çırağan Palace (now a hotel), Rumeli Hisarı fortress (1452), the first Bosphorus bridge, forested hillsides, and wooden yalıs. Cost: approximately €3 each way
Sultanahmet (Blue Mosque) and Historic Peninsula
Istanbul's Historic Core — Three Empires in One DistrictThe Sultanahmet district — occupying the tip of Istanbul's European peninsula between the Sea of Marmara and the Golden Horn — contains one of the world's greatest concentrations of historic monuments: Hagia Sophia, Topkapi Palace, the Blue Mosque (Sultanahmet Camii, 1616), the Hippodrome of Constantinople (now Sultanahmet Square, with its 4th-century obelisks), the Basilica Cistern (Yerebatan Sarnıcı, a 6th-century underground reservoir for 80,000 m³ of water), the Archaeological Museum complex, and the Byzantine remnants of the old city walls.
The Blue Mosque's Six Minarets
The Sultan Ahmed Mosque (Blue Mosque) — built by Sultan Ahmed I between 1609 and 1616 — was the first mosque in the Ottoman Empire built with six minarets, a number previously reserved for the mosque at Mecca. The Sultan had to fund an extra minaret at Mecca to resolve the controversy. Inside, 21,043 hand-painted İznik tiles in more than 50 different tulip designs give the mosque its 'Blue' name from their predominantly blue colouration in natural light
How to Find Cheap Flights to Istanbul
Turkish Airlines via Istanbul Is Often the Cheapest US-to-Europe Connection
Turkish Airlines routes many intercontinental passengers through Istanbul Airport (IST), making the IST hub one of the most affordable connection points from North America to European, African, and Asian destinations. A New York–Istanbul–elsewhere ticket on Turkish Airlines is frequently cheaper than competing European hub connections. If Istanbul is your destination rather than a connection, Turkish Airlines' own fares from the US are often excellent value.
Istanbul's Two Airports — IST (New) Is the Main Hub, SAW (Sabiha Gökçen) for Budget
Istanbul has two airports: Istanbul Airport (IST, European side, 45 km from centre) is the main hub used by Turkish Airlines and full-service carriers. Sabiha Gökçen Airport (SAW, Asian side, 55 km from European centre) is used by Pegasus Airlines, Ryanair, and other budget carriers — offering cheaper fares but a longer, more complex transfer into the city. Factor in transfer cost and time when comparing IST vs. SAW fares.
Book Istanbul Hotels in Sultanahmet or Beyoğlu for the Best Tourist Access
Sultanahmet (near Hagia Sophia and Topkapi) is the most convenient location for history and monument access. Beyoğlu (Taksim area, across the Golden Horn) has Istanbul's best restaurants, bars, and contemporary culture. Both are connected by tram to each other and to the Grand Bazaar. Avoid booking in the airport hotel zone (distant from everything) — Istanbul's centre is where you want to be.
Turkish Lira Makes Istanbul One of Europe's Best-Value Destinations
Currency depreciation over recent years has made Istanbul exceptionally affordable for visitors with USD, EUR, or GBP. Excellent restaurant meals cost $5–15, hotels from $50–120/night, transport from $0.50 per trip. A week in Istanbul on a mid-range budget that would be very tight in Paris or London is genuinely comfortable. This represents unusual value for a city of Istanbul's cultural richness.

It allows stays of up to 90 days within 180 days and is processed online in minutes. Carry a printed or digital copy. Turkey uses the Turkish Lira (₺); the emergency number is 112. Turkey is not part of the EU or Schengen Area.
What is Istanbul famous for?
Istanbul — the only city in the world on two continents (Europe and Asia) — is famous for Hagia Sophia (the 6th-century Byzantine cathedral and Ottoman mosque), Topkapi Palace (Ottoman imperial seat for 400 years), the Blue Mosque, the Grand Bazaar (world's oldest covered market), the Bosphorus Strait, Turkish cuisine, and as a bridge between European and Asian cultures. Istanbul was the capital of the Byzantine Empire (Constantinople) and the Ottoman Empire — two of the most important empires in world history.
What is the best time to visit Istanbul?
April–May and September–October for the best weather (18–24°C), moderate crowds, and full-service tourism at pleasant prices. June–August is hot (28–33°C), crowded, and expensive — but the Bosphorus cruises and outdoor dining are at their most vibrant. November–March for low prices, occasional mist over the Bosphorus (beautiful), and the most authentic non-touristic Istanbul experience. Ramadan (moveable feast) offers a remarkable atmosphere in the city's historic mosque districts — iftar tables and night prayers at Hagia Sophia and the Blue Mosque.
Is Istanbul safe for tourists?
Istanbul is generally safe for tourists in the main visitor areas (Sultanahmet, Beyoğlu, Beşiktaş, Kadıköy). Standard urban precautions apply — beware of carpet shop scams in Sultanahmet (never feel obligated to buy after accepting tea), use licensed taxis or apps (Bitaksi, Uber), and keep valuables secure in crowded market areas. The main tourist areas have a strong police presence. Check current UK/US government travel advisories for Turkey before travelling, as the security situation can change.
