This is by far the most sought after way for international tourists to travel. You can book tickets on lanes operated by the top airlines like American Airlines, British Airways, Air India, KLM Royal Dutch, Etihad and many others. The Istanbul Ataturk International airport is the busiest and constantly sees people fly in from cities like London, Berlin, Tokyo, Mumbai and many others.
If you are already in Turkiye, you can use domestic flights and shuttle between the many airports here.
Overland modes of transportation are an option if you are in any of the neighbouring countries.
If you prefer travelling via water, you can take ferries from neighbouring and nearby countries like Greece and Italy. Cruises are also a luxurious option from these destinations.
