EaseMyTrip is enabling users to book flights via WhatsApp, after integrating with the messaging platform.
Customers send their requests to the India-based online travel company and receive fare quotes back via the EaseMyTrip bot on the Facebook-owned WhatsApp platform.
The company also keeps users informed of price reduction or increases and dates when fares may be cheaper.
KLM claimed an airline first with its integration with WhatsApp for Business back in 2017 and uses the platform for confirmations and boarding passes as well as booking requests.
The carriers says it is getting 15,000 new subscribers every day.
TIC, a specialist in B2C communications technology, integrated WhatsApp last year, enabling its airport customers to communicate with passengers on flights and other services via the platform.
The messaging service is also adopted across the hotel industry but predominantly for post-booking services.
Tiago Araujo, co-founder and CEO of hotel chatbot HiJiffy, says guests use WhatsApp to request services such as transfers and upgrades as well as for Frequently Asked Questions.
He adds that once at the property, the platform is used instead of contacting reception.
Recent research from B2C messaging platform Zingle revealed that two thirds of consumers had interacted with a chatbot or digital assistant in the preceding month.
