Loading full-day schedule…
Planning estimates, not measured passenger counts. Flight capacities cannot be established from flight numbers or codeshare counts. Every capacity below is a documented assumption or your override.
Rolling hour = greatest sum over any 60 consecutive schedule minutes. Absolute occupancy = greatest simultaneous number across zones at the same minute, not the sum of each zone's separate peak. Midnight boundaries omit adjacent-day flights; totals count passenger journeys, not unique people.

Flight capacity assumptions
Base: IndiGo A320 scenario 186 seats; 6E7xxx regional heuristic 78 (not equipment confirmation); Air India 164; Air India Express / Akasa / SpiceJet 189; FLY91 72; Alliance Air 70; Star Air 76. International mixed fleets use 180 or 300, Emirates 354; upper/lower cases expose equipment uncertainty. See per-flight exports. No aircraft has been confirmed for this dated service.
Flight-number and codeshare audit
| Marketing alias | Primary board flight | Direction | Time IST | Route |
|---|
Source originals remain unchanged. Format validation is not operational verification. A32071 is parsed as carrier A3 + flight 2071, not an A320 aircraft capacity. AF194 at 00:50 and 23:35 remains two dated occurrences. Possible 5F/SG duplicate operations are not declared verified codeshares.
Method and evidence
Departure cohorts pass sequentially through check-in 30 min, security 15, international departure processing 20, retail 20, lounge 30, gate circulation 10, boarding 15; departure cohorts end 5–25 minutes before STD. Arrival cohorts enter 10–30 minutes after STA, then corridor 10, international immigration 25, baggage 25 for 80%, customs 5 when international, meet-and-greet 10 and ground transport 10. Dwell multiplier scales processing time. No shared queues, visitors, staff or measured show-up profiles included. Undefined geography uses the international processing path conservatively. Unresolved terminals remain a separate bucket.
