Waiting at pickup. Your captain's free waiting starts when they arrive at the pickup — confirmed by their phone's location — or at the time you booked, if that's later. The free minutes and the per-minute rate depend on the ride type: a bike or Pink ride costs less a minute than a cab, and Premium and XL a little more. Waiting is charged up to a limit (30 minutes on most ride types), and if your captain's arrival couldn't be confirmed, no waiting is charged at all. It's charged because that time is a captain waiting rather than earning.
Delays during the trip. If a trip takes substantially longer than estimated — more than 10 minutes beyond the estimate, or over 1.5× the estimated duration — a delay charge of ₹2 per minute applies to the excess. Time spent waiting at your stops doesn't count as delay.
Waiting is never surged. Every wait and delay appears as its own line in your fare breakdown, so you can always see what you were charged and why.
