Normally, the allowance set by Air India Express is conditioned by the booking class of the flight and the duration of the route. Generally, Economy passengers are allowed to take 15 kg of cabin baggage and 20-35 kg of baggage to be checked. Business passengers are typically allowed more cabin baggage and are usually allowed between 30 and 40 kg of checked baggage . However, you should confirm this by checking the email with your booking confirmation. In certain situations, the airline can restrict baggage allowance depending on the flight time, type of fare, or your booking status.
