Mumbai's airport express Chalo bus services have been discontinued due to poor passenger response, despite pending approval from the BEST undertaking. Operating 230 trips daily at 30-minute intervals to Colaba, Kharghar, and Thane, the services faced financial challenges, according to a BEST official. Passengers were informed of the suspension after inquiring about the absence of services. Chalo cited operational challenges for the discontinuation, while a BEST spokesperson stated that closure approval had not been granted yet. A meeting is scheduled on Friday to gather details from Chalo management.
