Compare on Comfort

In the AC III tier, a normal berth will accommodate three people on each side. The middle seat in the AC III tier is foldable, and if the passengers sitting below you cooperate, three people can travel on the lower seat during the day. But most people don’t agree.

The person sitting on the lower berth can relax and sleep during the journey, and the passenger in the upper berth usually climbs up and has to lie down as there is no back support and cannot sit for long. However, there is often a dispute over who will use the middle seat in the AC III tier.

In the AC II tier, in each compartment, there are four passengers on one side of the aisle and two on the other side. You can sit more comfortably in the AC II tier, as each berth can accommodate two people instead of three.

Travelling in the AC II tier is easy and comfortable, as there is no middle seat on the aisle side. While in the AC III tier, you have six passengers on one side of the aisle and two on the other side. You will share the compartment with 8 people instead of 6.
