PNR confirmation prediction uses statistical analysis of:
- Historical booking patterns for the same train + route + class
- Average cancellation rates (typically 10-20% before chart prep)
- Days remaining until departure
- Tatkal pattern (TQWL is harder to predict)
- Seasonality (festivals, holidays)
Accuracy varies by waitlist type:
- GNWL: 75-85% accurate
- PQWL: 60-70% (smaller pool, more variance)
- TQWL: 50-60% (limited Tatkal cancellations)
- RLWL: 60-70%
Tips for better confirmation:
- Book 60+ days in advance from origin (best GNWL chances)
- Avoid PQWL — book from origin station instead
- Tatkal is hit-or-miss
- Premium trains (Rajdhani, Shatabdi) have lower cancellation rates
