Delhi Metro passengers can now conveniently travel on the Airport Line using a newly launched ticketing service based on WhatsApp. This digital system enables commuters to receive QR code-based tickets directly through WhatsApp. The Delhi Metro Rail Corporation introduced this service on Tuesday. By adding the official DMRC WhatsApp number (9650855800) to their contact list, passengers can use the dedicated WhatsApp chatbot to generate QR code-based tickets in English or Hindi. This feature is especially beneficial for national and international travellers using the Airport Line, as they can conveniently purchase and use tickets directly from their smartphones. Each passenger can generate a maximum of six QR code-based tickets for single or group journeys, which remain valid until the end of the business day. However, passengers must exit within 65 minutes of reaching their destination station or within 30 minutes if exiting at the source station. The service is available during business hours, and a nominal convenience fee is charged for credit or debit card transactions, while UPI-based transactions are fee-free.
