Budget carriers charging Rs 200 less for no check in baggage

Realizing that some people travel by air only because they can conveniently and safely transport a lot of luggage with less effort, and without hiring a coolie, now many budget carriers are offering two different tickets on the same route, one a lite ticket for only 7 kg of hand baggage, and a normal ticket which is priced at Rs 200 more than the lite ticket.
