A long-haul holiday is generally considered to be one with a flight time of six hours or more. How long should a long-haul holiday be? Long-haul holidays are usually a week to two weeks long.

TUI generally classifies any flight that is over 7 hours in duration as "long-haul." In 2026, this category primarily includes destinations in the Caribbean (like Jamaica, Mexico's Caribbean Coast, and the Dominican Republic), the Indian Ocean (Maldives, Mauritius, and Goa), and Southeast Asia (Thailand and Vietnam), as well as Florida in the United States. When you fly long-haul with TUI, you typically travel on their flagship Boeing 787 Dreamliner, which offers a different onboard experience than their short-haul European hops. Long-haul passengers receive complimentary meals and drinks, a seat-back entertainment system with movies and games, and a larger checked luggage allowance (usually 20kg–23kg included in packages). TUI also offers a "Premium" cabin upgrade on these routes, which includes more legroom, upgraded dining, and priority airport services. In contrast, "mid-haul" for TUI usually covers 4 to 6-hour flights to places like the Canary Islands, Egypt, or Cape Verde, where the service is more streamlined and may not include the full long-haul meal and entertainment suite.
