In 2026, the duration you can stay in Doha for transit depends on your nationality and your airline. Most travelers transiting through Hamad International Airport (DOH) on Qatar Airways can take advantage of the Free 96-Hour Transit Visa, which allows for a stay of up to 4 days (96 hours) between flights. To qualify, your layover must be at least 5 hours long, and you must have a confirmed onward ticket to a third country. For shorter transits where you don't wish to clear immigration, you can stay in the airport transit area for up to 24 hours. If you want a longer stay, Qatar offers a "Stopover Program" in 2026 that provides discounted 4-star and 5-star hotel stays for up to 4 nights. It is a "pro" requirement to apply for the transit visa online at least 7 days before your journey. If you are from one of the 100+ "visa-exempt" countries, you may not even need the specific transit visa and can instead enter on a standard visa-on-arrival for up to 30 or 90 days, depending on your passport.
