Ultra-long flights are now a reality, with some flights taking up to 19 hours non-stop. Airlines are focusing on direct routes, skipping stops to connect distant cities faster, even if it means spending more time in the air.
In 2025, it is clear that ultra-long-haul travel will dominate global aviation trends. These flights connect major business centers across continents, testing passenger comfort and demonstrating how far modern aircraft technology has advanced in recent years.
