An "onwards flight ticket" is a confirmed ticket for a flight that will take you somewhere other than your initial destination. When someone travels to a country on a tourist visa or visa-free entry, it is usually required by airlines and immigration officials as evidence of intent to depart. For instance, if you are visiting a country on a tourist visa or if you are arriving without a visa, immigration officials may want proof that you will not be staying longer than permitted. You can show that you intend to leave the country before the end of your visa or entry period by presenting an onward travel ticket. You can buy an onward ticket for about INR 350, or $5, in less than 10 minutes.
