Terminal 3 is a real upgrade
The main international terminal is spacious, modern, and handles big crowds with room to breathe.
Security and document checks can be thorough to the point of slowing everything down.
Delhi's Terminal 3 genuinely surprised me with how bright and well organized it felt. Traveling with my parents and kids, we appreciated the space and the variety of food that suited everyone. The multiple layers of security take time, so arrive early and pack your patience.
