In 2026, airports generally do not provide "free" accommodation directly, but many major hubs feature on-site transit hotels (like YOTELAIR or Aerotel) that you can book by the hour. However, several world-class airlines offer "STPC" (Service for Through Passengers on Connection) programs. For example, Turkish Airlines, Emirates, and Qatar Airways often provide a free hotel room, meals, and transfers if your layover is between 8 and 24 hours and there was no shorter connection available. At hubs like Singapore Changi or Seoul Incheon, you may find dedicated "rest zones" with reclining chairs or nap pods available for a small fee. If your layover is caused by an airline delay or cancellation within their control, international passenger rights (such as EU261) mandate that the airline must provide you with hotel accommodation and transport at no cost. Always check your specific airline's "Stopover" policy before booking to see if you qualify for a complimentary stay.
