Why Airlines Reject Legitimate Claims

Let's be blunt: airlines have a financial incentive to reject your claim. Every denied claim saves them €250-€600 per passenger. Industry insiders estimate that 40-60% of initial rejections are invalid - airlines simply hope you won't challenge them.

The Economics of Rejection

Airlines employ dedicated teams whose job is to minimize compensation payouts. They use:

  • Vague rejection letters - "extraordinary circumstances" without specifics
  • Incorrect legal interpretations - claiming technical faults are extraordinary
  • Delay tactics - hoping you give up during lengthy "investigations"
  • Betting on ignorance - assuming passengers don't know EU case law

Most Common Rejection Reasons (And Why They're Often Wrong)

"Technical Fault"

Airlines claim: "Extraordinary circumstances - unexpected technical issue."

✓ REALITY: 95% of technical faults require full compensation (EU Court ruling)

"Crew Sickness"

Airlines claim: "Extraordinary circumstances - pilot called in sick."

✓ REALITY: Normal crew sickness is operational risk - compensation required

"Bird Strike"

Airlines claim: "Extraordinary circumstances - unpredictable wildlife collision."

⚠ GRAY AREA: Usually compensable unless truly exceptional circumstances

"Airport Strike"

Airlines claim: "Extraordinary circumstances - security staff strike."

✗ VALID: Airport/ATC strikes ARE extraordinary (no compensation)

Key Insight: The "Reasonable Measures" Test

Even IF an event qualifies as "extraordinary circumstances," airlines must prove they took all reasonable measures to avoid the delay. This means:

  • ✓ Did they try to rebook you on another airline?
  • ✓ Did they deploy backup aircraft?
  • ✓ Did they have maintenance protocols followed correctly?
  • ✓ Did they have adequate crew reserves?

If the answer to ANY of these is "no" - you're entitled to compensation even if the root cause was extraordinary.

What Actually Qualifies as "Extraordinary Circumstances"?

Under EU Regulation 261/2004, "extraordinary circumstances" are events that are:

1️⃣

Beyond Control

Not inherent to the airline's normal operations

2️⃣

Unpreventable

Could not be avoided even with all reasonable measures

3️⃣

Exceptional

Not a routine or foreseeable operational issue

Valid Extraordinary Circumstances (No Compensation)

Severe Weather

Storms, hurricanes, volcanic ash, heavy snow making flight unsafe. Not "any bad weather" - must be severe enough to prevent safe operations.

Air Traffic Control Restrictions

ATC strikes, staff shortages, slot restrictions imposed by authorities (not the airline).

Security Threats

Bomb threats, unruly passengers requiring police, security breaches at the airport.

Political Instability

Wars, terrorism, civil unrest, government-ordered airspace closures.

Airport Staff Strikes

Strikes by baggage handlers, security screeners, customs, refueling staff (external to airline).

Invalid "Extraordinary Circumstances" (Compensation Required)

Technical/Mechanical Problems

95% of technical faults are the airline's responsibility. Engine failures, hydraulic issues, software glitches, component replacements - all require compensation unless it's a hidden manufacturing defect (see below).

Crew Shortages

Pilot/cabin crew sickness (unless mass outbreak), scheduling errors, crew duty time limits, late crew arrivals - all operational risks requiring compensation.

Airline Staff Strikes

Strikes by the airline's own pilots, cabin crew, or ground staff ARE the airline's responsibility. Full compensation applies (unlike airport staff strikes).

Overbooking

Selling more tickets than seats is a deliberate commercial practice. Airlines must compensate denied boarding passengers at 250-400% of ticket price.

Previous Flight Delays (Knock-on Effects)

"Your aircraft is delayed from a previous route" - airlines try to claim extraordinary circumstances, but unless the ORIGINAL delay was extraordinary, you're owed compensation.

Technical Faults: When You STILL Get Paid

This is where airlines lie the most. They'll claim "unforeseen technical issue" or "unexpected maintenance requirement" as extraordinary circumstances. Don't believe it.

The Wallentin-Hermann Precedent (ECJ Case C-549/07)

In 2008, the EU Court of Justice ruled definitively: Technical problems are NOT extraordinary circumstances because:

  • Aircraft maintenance is an inherent part of airline operations
  • Airlines have control over maintenance schedules and spare parts
  • Component failures are foreseeable risks of operating aircraft

"Technical problems which come to light during maintenance of aircraft or on account of failure to carry out such maintenance cannot constitute, in themselves, 'extraordinary circumstances'."

Technical Faults That Require Compensation (95% of Cases)

✓ Engine Problems

Engine failures, turbine blade cracks, oil leaks, compressor stalls

✓ Hydraulic System Failures

Landing gear issues, flap malfunctions, brake system problems

✓ Electrical/Software Issues

Avionics failures, flight computer errors, sensor malfunctions

✓ Structural Problems

Fuselage cracks, window seal failures, door mechanism issues

✓ Cabin Systems

Air conditioning failures, pressurization problems, oxygen system issues

✓ Navigation Equipment

GPS failures, radio communication problems, autopilot malfunctions

Real Example: How Airlines Word Technical Fault Rejections

❌ Airline's Vague Rejection Letter:

"Your flight was delayed due to an unforeseen technical issue discovered during pre-flight checks. This constitutes extraordinary circumstances beyond our control under EU261/2004."

✅ Your Proper Appeal Response:

"According to ECJ Case C-549/07 Wallentin-Hermann, technical problems 'cannot constitute, in themselves, extraordinary circumstances.' Unless you can prove this was a hidden manufacturing defect announced by Boeing/Airbus (which would be public knowledge), I am legally entitled to €[X] compensation. Payment expected within 14 days."

Crew Sickness & Rostering Issues

"Our pilot called in sick" is another common rejection excuse. While sudden illness is unpredictable, airlines must maintain adequate crew reserves - it's part of their operational duty.

The Pešková Ruling (ECJ Case C-315/15)

In 2017, the EU Court clarified: Crew illness is generally NOT extraordinary unless:

  • 1The illness was sudden and unforeseeable (not pre-existing or known condition)
  • 2The airline took all reasonable measures to secure replacement crew
  • 3It was exceptional - not routine sickness that airlines should plan for

When Crew Sickness DOES Require Compensation

Single Crew Member Illness

One pilot or crew member calling in sick is a normal operational risk. Airlines should have standby crew available.

Crew Duty Time Violations

"Crew ran out of hours due to previous delays" - this is a rostering failure, not extraordinary circumstances.

Insufficient Standby Crew

"No replacement crew available" proves the airline failed to maintain adequate reserves - compensation required.

Crew Stuck at Another Airport

"Crew delayed on inbound flight" - knock-on effect from airline's own operations. Not extraordinary.

Rare Cases: When Crew Sickness IS Extraordinary

Mass Crew Outbreak

Multiple crew members falling ill simultaneously (e.g., food poisoning affecting entire crew) - genuinely unforeseeable.

Medical Emergency During Flight

Crew member incapacitated mid-flight requiring emergency landing - truly exceptional event.

💡 Pro Tip: Challenge Crew Sickness Claims

If an airline rejects your claim citing crew sickness, demand specifics:

  • ✓ How many crew members were affected?
  • ✓ When did the illness occur (sudden or known in advance)?
  • ✓ What efforts were made to secure replacement crew?
  • ✓ Why were no standby crew available?

Airlines rarely provide detailed answers because it would expose their lack of reasonable measures.

Bird Strikes: The Gray Area

Bird strikes are one of the trickiest rejection reasons because they're genuinely unpredictable - but that doesn't automatically make them extraordinary circumstances.

The van der Lans Ruling (ECJ Case C-257/14)

In 2015, the EU Court ruled on bird strike compensation: Bird strikes are generally NOT extraordinary because:

  • Bird collisions are an inherent risk of aviation (happen regularly)
  • Airports have wildlife control measures to minimize bird activity
  • Aircraft are designed to withstand bird strikes (reinforced windshields, engine ingestion tests)

"Collision with birds must be regarded as an event which is inherent in the normal exercise of the activity of the air carrier concerned."

When Bird Strikes Require Compensation (Most Cases)

Single Bird Strike

One or a few birds hitting the aircraft - normal operational risk. Compensation applies unless damage was exceptional.

Routine Engine Ingestion

Bird sucked into engine requiring inspection - engines are tested for this scenario. Not extraordinary.

Airport Known for Bird Activity

If the airport has frequent bird strikes (near wetlands/landfills), it's a foreseeable risk - compensation required.

Rare Exceptional Cases (No Compensation)

Multiple Engine Failure

Large flock causing catastrophic damage to multiple engines simultaneously (e.g., "Miracle on the Hudson" scenario).

Unprecedented Swarm

Massive, never-before-seen bird migration overwhelming airport wildlife control (extremely rare).

✓ High Success Rate: 75-80%

Bird strike compensation claims have a high success rate when challenged because:

  • ✓ van der Lans ruling clearly favors passengers
  • ✓ Airlines struggle to prove bird strike was "exceptional"
  • ✓ Most strikes are routine, predictable events

Hidden Manufacturing Defects: The ONE Exception

Here's the only technical fault scenario where airlines legitimately don't pay: hidden manufacturing defects discovered by the aircraft manufacturer (not the airline) after the plane entered service.

What Qualifies as a "Hidden Manufacturing Defect"?

1
Design or Production Flaw: A systematic problem affecting multiple aircraft of the same model, not a one-off component failure.
2
Unknown to Airline: The defect was not detectable through normal maintenance, inspections, or pre-flight checks.
3
Manufacturer Announcement: Boeing, Airbus, or engine maker issued an Airworthiness Directive or Service Bulletin identifying the flaw.
4
Publicly Documented: The defect should be news-worthy (aviation authorities, press, safety databases).

Real Examples of Valid Hidden Defects (No Compensation)

Boeing 787 Battery Fires (2013)

Lithium-ion battery design flaw causing fires/smoke - entire fleet grounded by FAA. Unknown to airlines until multiple incidents.

✗ Valid extraordinary circumstance

Boeing 737 MAX MCAS Software (2019-2020)

Flight control software flaw leading to crashes - global grounding by authorities. Hidden design defect.

✗ Valid extraordinary circumstance

Rolls-Royce Trent 1000 Engine Issues (2016-2018)

Turbine blade deterioration requiring manufacturer-mandated inspections - discovered post-certification.

✗ Valid extraordinary circumstance

What IS NOT a Hidden Defect (Compensation Required)

Routine Component Failures

"Hydraulic pump failed" or "sensor malfunctioned" - normal wear-and-tear, not hidden defects.

Maintenance-Detected Issues

"Found during inspection" - if discovered by airline maintenance, it's their responsibility.

Single Aircraft Problem

"Issue with this specific plane" - not a fleet-wide manufacturer defect, so not extraordinary.

Software Glitches/Updates

"Computer system error" - unless a manufacturer-announced flaw (like 737 MAX), it's the airline's problem.

🔍 How to Verify: Public Safety Databases

If an airline claims "hidden manufacturing defect," you can verify:

  • EASA Safety Publications (Europe): easa.europa.eu/safety-directives
  • FAA Airworthiness Directives (US): faa.gov/aircraft/safety/alerts
  • Aviation Safety Network: aviation-safety.net
  • News archives: Search "[aircraft type] defect [date]" on Google News

If you can't find public documentation of a manufacturer-announced fleet-wide defect, the airline is lying.

Airport vs Airline Strikes: Who Pays?

Strikes are straightforward once you understand the key principle: Were the striking workers employed by the airline or by external parties?

Airport/ATC Strikes

✗ NO COMPENSATION (Valid Extraordinary Circumstances)

Strikes by parties external to the airline:

  • Air traffic controllers (ATC)
  • Airport security screeners
  • Baggage handlers (if airport-employed)
  • Immigration/customs officers
  • Refueling company workers
  • Airport cleaning/catering staff

Airline Staff Strikes

✓ FULL COMPENSATION REQUIRED (Not Extraordinary)

Strikes by the airline's own employees:

  • Pilots (cockpit crew)
  • Flight attendants (cabin crew)
  • Airline ground staff
  • Airline maintenance technicians
  • Check-in desk staff (if airline-employed)
  • Baggage handlers (if airline-employed)

Legal Reasoning: Why the Distinction Matters

The EU Courts ruled that airlines are responsible for managing their internal labor relations. If pilots/crew strike:

  • It's a failure of internal management (labor negotiations, working conditions)
  • The airline has control over employment terms and can resolve disputes
  • NOT beyond the airline's control → NOT extraordinary circumstances

However, ATC/airport strikes are by third parties the airline cannot influence → Valid extraordinary circumstances.

Common Strike Rejection Tricks

Vague "Strike Action" Claims

Airlines say "strike" without specifying who was striking. This is intentional ambiguity.

Your Response: "Which specific party was on strike? Please provide documentation (strike notice, airport announcement, news article). If it was your own crew, compensation is required."

"Strike Threat" vs Actual Strike

Airlines cancel flights preemptively citing planned strikes that never happen.

Your Response: "A mere threat is not an extraordinary circumstance - the strike must actually occur. Did ATC/airport staff actually walk out? Prove it with official statements."

💡 Research Tip: Verify Strike Claims

Check if a strike actually happened:

  • Airport websites: Official strike announcements
  • ATC provider sites: NATS (UK), DSNA (France), DFS (Germany)
  • Eurocontrol: European ATC network disruptions
  • News archives: "[Airport name] strike [date]" on Google News

If you find no evidence of an external strike, demand compensation.

How to Challenge a Rejection (Step-by-Step)

Armed with the legal knowledge above, here's exactly how to fight back when an airline rejects your claim.

1

Review the Rejection Letter

Carefully analyze the airline's stated reason. Look for:

  • Vague language: "extraordinary circumstances" without specifics
  • Contradictions: Does it match your experience?
  • Missing details: No flight number, date, or specific fault listed
Red Flag: If the letter is generic and could apply to any flight, the airline is using a template to discourage appeals.
2

Gather Counter-Evidence

Build your case with concrete evidence:

✓ Flight Tracking Data

FlightRadar24, FlightAware - screenshot your flight history + other flights from same airline/airport

✓ Weather Reports

Aviation weather archives (aviationweather.gov) - prove weather was NOT severe that day

✓ Airport Announcements

Contact airport customer service - were there ATC issues/strikes that day?

✓ Passenger Testimonies

Social media, forums - what did other passengers hear/experience?
