Why charting matters
Charting finalises many passenger allocations and can change RAC, waitlist, coach and berth details. Some systems may show updates in stages.
Treat time as an estimate
Chart preparation varies by departure time, boarding point and operational instruction. Use the calculator for a decision window and recheck the official PNR record.
Make a decision checklist
Before the expected chart time, note your cancellation options, alternative travel plan, station reach time and how you will verify the final status.
