On-Time Performance

On-Time Performance (OTP) data transforms how you choose flights. Instead of picking the cheapest option or the most convenient time, you can factor in the actual reliability of each airline on each specific route — because an airline's global OTP statistic tells you almost nothing about what that airline is like on the specific route you're flying.

TrackMyWings aggregates on-time performance data at three levels: airline-wide (e.g., IndiGo's overall OTP across all routes), route-specific (e.g., IndiGo's OTP on DEL–BOM specifically), and time-of-day-specific (e.g., IndiGo's OTP on DEL–BOM for morning departures vs. evening departures). This granularity matters enormously in practice.

Consider this: IndiGo's overall OTP might be 78%. But on the DEL–BOM 6 PM departure, it might be 52% — because that departure is systematically caught in evening slot compression at both Delhi and Mumbai. The 7 AM departure on the same route might be 91%. If you have flexibility, the morning flight is dramatically more reliable. OTP data makes that visible.

For Indian travelers, on-time performance data is particularly valuable because Indian airlines have highly variable OTP across routes and times — far more variable than European or North American carriers on comparable routes. A route that's extremely reliable in winter might be completely unpredictable during monsoon. Our OTP data is broken down by month, so you can see seasonal patterns.

OTP data is also available for airports, not just airlines. Which is the most delay-prone airport for departures? Which has the best on-time record for arrivals? If you have a connection at an airport with poor OTP, that's a risk factor worth knowing before you book.

All On-Time Performance data is available for free. We believe travelers deserve access to this information when making booking decisions, not just after they've already bought a ticket.
