<h1>Airline Turmoil as Miscalculated Pilot Rosters Collide with New DGCA Flight Duty Time Limitations (FDTL) Rules</h1> India's largest airline is facing its most severe operational and regulatory crisis after widespread cancellations triggered by miscalculated pilot staffing under newly enforced Flight Duty Time Limitations (FDTL) issued by the Directorate General of Civil Aviation (DGCA). The DGCA, having fully implemented stricter rest and night-duty rules from November 1, 2025, has opened a formal inquiry, mandated fortnightly reports, and issued show-cause notices to the airline's chief executive and accountable manager for failure to ensure adequate arrangements for compliance. Under pressure from mass disruptions and fare spikes, regulators temporarily relaxed certain FDTL night-duty limits until February 10, 2026, imposed fare caps, and increased oversight, while the airline introduced refunds, fee waivers, and a crisis management board committee to restore normal operations.
