Current Context: Recently, India issued a Notice to Air Missions (NOTAM), closing its airspace to all Pakistan-registered, operated, or leased aircraft, including military flights, until May 23, 2025.

About Notice to Air Missions (NOTAM):

• A NOTAM is an official notice issued by aviation authorities to alert pilots and airlines about potential hazards or changes in flight operations.
• It provides information on changes in aeronautical facilities, services, procedures, or hazards essential for flight operations.

Implications:

• Indian airlines, such as Air India and IndiGo, are experiencing increased flight durations by up to 4 hours on routes to Europe and North America, leading to higher fuel consumption and operational costs.
• The closure signifies heightened diplomatic and military tensions between India and Pakistan, with both nations imposing reciprocal airspace restrictions.
