The accused, identified as Damanpreet Singh, owns a travel agency in central Delhi's Karol Bagh area.
He allegedly forged records and cheated customers of an international airline company, said a police official.
According to the police, Singh allegedly used to keep tab on clients who were loyal to British Airways as it would give 'points' to such flyers on the basis of distance travelled in a particular year.
Those points could again be collectively used as currency for buying fresh tickets pertaining to the same company.
He later utilised those points to buy international air tickets and sold them to other clients, charging them full amount for the same, said the police official.
Singh has been booked under Sections 420 (cheating), 468 (forgery) and 471 (forgery with respect to electronic documents) of IPC and relevant sections of IT Act, the official added.
