Flight Diversion Support
Alternate Airport Coordination
What Is a Flight Diversion?
A flight diversion occurs when an aircraft cannot land at its scheduled destination and must instead land at an alternate airport. Diversions are a normal part of aviation operations — they are not inherently emergencies, but they do create immediate operational, logistical, and potentially regulatory challenges that the operator must manage quickly.
Common causes of flight diversions
- Weather at the destination airport — fog, crosswind limits, thunderstorm activity
- Medical emergency on board requiring immediate landing
- Technical issue with the aircraft requiring precautionary diversion
- Airspace closure or temporary flight restriction
- Airport operational issues — runway closures, equipment failures
- Fuel calculation requiring an unplanned refuelling stop
Why Speed Matters in Diversion Response
Every hour on the ground at an alternate airport has a cost: fuel, crew duty time, passenger accommodation, and schedule disruption all compound quickly. Without a ground coordinator engaged within minutes of a diversion, operators face a cascade of individual phone calls — to ground handlers, hotels, fuel suppliers, and permit authorities — each waiting for the previous call to complete.
ASM's model is parallel coordination: the moment a diversion is confirmed, our team contacts all relevant suppliers simultaneously. Ground handlers, hotels, fuel suppliers, and permit authorities are all engaged at the same time. This parallel approach is the primary reason diversion response time is faster when managed through ASM than when handled in-house.
What ASM Coordinates During a Diversion
Alternate Airport Confirmation
Immediate assessment of the alternate airport's handling capability, fuel availability, and operational status. ASM briefs local suppliers and confirms their availability to support the inbound aircraft before it lands.
Emergency Permits & Regulatory Notifications
Where the alternate is in a different regulatory jurisdiction, ASM coordinates any required emergency landing authorisation or regulatory notification on an urgent basis. Civil aviation authorities at the alternate country or airport are notified as required.
Ground Handling & Fuelling
Full ground handling coordination at the alternate — aircraft handling, passenger services, and fuel delivery. ASM supervises quality and reports discrepancies to the operator throughout the ground stop.
Crew HOTAC
Rapid hotel booking for flight crew near the alternate airport. ASM's HOTAC network covers most major diversion destinations. Where standard hotel options are unavailable, contingency alternatives are activated immediately.
Passenger Welfare
Hotel accommodation, ground transport, meal arrangements, and communication support for passengers. ASM coordinates passenger welfare in line with the airline's customer service standards and applicable regulatory requirements.
Onward Flight Coordination
Where the aircraft is airworthy, ASM supports planning and permit coordination for the continuation of the mission from the alternate airport — including an updated flight plan, any required permits for the revised routing, and re-confirmation of ground services at the original destination.

FAQs - Flight Diversion Support
Q: What is a flight diversion?
A: A flight diversion is when an aircraft is redirected to land at an airport other than its planned destination — typically due to weather, a medical emergency, a technical issue, or an airspace restriction. Diversions are a normal, pre-planned contingency in commercial aviation.
Q: What causes a flight to divert?
A: Common causes include: adverse weather at the destination (crosswind limits, low visibility, thunderstorms), medical emergencies requiring immediate landing, technical issues on board, airspace restrictions or temporary flight restrictions, fuel requirements, and airport operational issues such as runway closures.
Q: How quickly can ASM respond to a diversion?
A: Immediately. ASM's 24/7 operations team is always staffed and begins coordinating from the moment a diversion is confirmed. Ground handlers, hotels, and fuel suppliers are contacted simultaneously to minimise ground time.
Q: Does ASM coordinate permits for diversions to foreign countries?
A: Yes. Where the alternate airport is in a different country or regulatory jurisdiction, ASM coordinates any required emergency landing authorisation or regulatory notification on an urgent basis.
Q: Can ASM handle passenger welfare during a diversion?
A: Yes. ASM coordinates hotel accommodation, ground transport, meal arrangements, and general passenger welfare support in line with the airline's instructions and applicable EU261 or equivalent regulatory requirements.
Q: Does ASM support cargo flight diversions?
A: Yes. ASM supports cargo and freighter diversions including customs notifications, documentation support, and onward routing coordination.
Q: Can ASM support diversions to remote or non-hub airports?
A: Yes, though supplier availability varies by location. ASM will advise on available options and work every available contact to support the operation, even at challenging alternate locations.
Q: What is the difference between a diversion and an emergency landing?
A: A diversion is a redirect to an alternate airport for operational reasons, which may or may not involve an emergency. An emergency landing typically involves a declared emergency (MAYDAY or PAN PAN) and an immediate landing at the nearest suitable airport. Both require rapid ground coordination.
Q: Does ASM provide post-diversion onward flight support?
A: Yes. Where the aircraft is serviceable, ASM supports planning and permit coordination for the continuation of the original mission from the alternate airport.
