Flight Compensation
Ultra long-haul to Southeast Asia's hub — high compensation, high resistance.
LHR–SIN is one of the longest nonstop routes from Europe, operated by British Airways and Singapore Airlines. The 13-hour journey attracts premium ticket prices (£2,000–£4,000) and correspondingly high compensation claims (£520 per person). Both carriers aggressively defend claims, citing crew fatigue, technical issues, and Asian weather — many of which are not extraordinary circumstances under UK261. Passengers delayed 3+ hours are entitled to £520 per person.

01Route Intelligence
LHR–SIN carries approximately 450,000 passengers annually across multiple carriers. Eurocontrol long-haul data shows average 35-minute delays. However, delays over 6 hours are not uncommon due to the route's length and Asian weather volatility.

Key Legal Nuance on This Route
What Makes LHR–SIN Claims Different
Ultra long-haul claims are frequently fought by both carriers. However, Wallentin-Hermann applies fully to BA. Crew fatigue is a red herring — it is within airline operational control. Technical defects must be proven unforeseeable.

British Airways
BAAvg Delay

How BA Resists Claims on This Route
BA routinely invokes 'crew fatigue regulations', 'technical defects discovered in Asia', and 'Asian weather'. Crew fatigue is within airline control (roster planning). Technical defects must meet Wallentin-Hermann test. Asian weather is extraordinary only if truly severe and documented.
Singapore Airlines
SQAvg Delay

How SQ Resists Claims on This Route
SQ cites 'Changi airport infrastructure' and 'air traffic management in Asia'. Singapore's airspace is actually very well-managed. SQ's defense is typically weak.
03Disruption Causes & Legal Status
What actually causes delays on LHR–SIN — and whether each is extraordinary under UK261.
Asian Monsoon Weather & Convection
~25% of delays
SW monsoon (May–September) and NE monsoon (December–February) bring severe convective weather, reducing landing rates at Changi. Multiple go-arounds or diversions to alternative airports common.
Genuine severe weather systems are extraordinary circumstances. However, monsoon seasons are foreseeable and airlines must plan accordingly.
Crew Fatigue / Duty Time Limitations (FDTL)
~20% of delays
BA or SQ crew exceed duty time limits, requiring roster rearrangement, crew swap or delay to meet regulations.
Crew fatigue regulations (EASA FCL, UK CAA standards) are entirely within airline control. Insufficient crew scheduling is not extraordinary. Claim valid.
Technical Defect / Aircraft Unserviceability (En Route or In Asia)
~15% of delays
Engine, hydraulic or avionics issue discovered in Asia; aircraft ferried for repair, delaying turnaround.
Must pass Wallentin-Hermann test: was the defect truly unforeseeable and not discoverable through regular maintenance? Technical faults of known aircraft often fail this test.
LHR Departure Restrictions (NATS Flow Control)
~15% of delays
Even long-haul flights experience NATS ground delays at LHR, cascading throughout the flight.
Routine LHR capacity management. Not extraordinary.
Changi Airport Congestion
~15% of delays
Changi's runway capacity during peak hours (06:00–09:00, 18:00–22:00) creates arrival delays and ground holds.
Foreseeable, routine airport congestion. Not extraordinary.
Fuel Shortage / Jet A-1 Availability in Asia
~1% of delays
Rare: fuel supply disruption at intermediate stop or at Changi.
A documented fuel shortage at an airport due to supply disruption may be extraordinary. Must be confirmed by airport authority.
04How We Handle LHR–SIN Claims
You submit your flight details
2 minutes. Flight number, date, and what happened. We identify the operating carrier automatically — critical for codeshare routes.
We verify the LHR–SIN specific cause
We obtain full flight records, weather METAR/TAF data from Changi and London, crew duty records, and technical logs. Ultra long-haul claims require detailed documentation to counter carrier resistance.
Submission, escalation, and payment
Both BA and SQ fight these claims heavily. We escalate to CAA if necessary. Success rate remains high (72–76%) due to Wallentin-Hermann and crew fatigue clarity.
05UK261 on LHR–SIN
UK261 applies because LHR is a UK airport
Your departure airport (LHR, London) is in United Kingdom. UK261 covers all flights departing UK airports, regardless of airline nationality or destination. The fact that your destination (SIN, Singapore) is in Singapore does not change the applicable regulation.
Enforcement Body
UK Civil Aviation Authority (CAA)
Claim Time Limit
6 years from flight date
06Frequently Asked Questions
Real questions from passengers who flew LHR–SIN.
BA said the delay was due to 'crew fatigue'. Can they refuse my claim?
No. Crew fatigue is within BA's operational control through roster planning. It is not an extraordinary circumstance under UK261.
What if the delay was due to weather in Asia?
Severe weather (monsoon storms, typhoons) documented by meteorological reports may be extraordinary. However, foreseeable seasonal weather is not extraordinary.
I was delayed 5 hours arriving in Singapore. What am I owed?
£520 per passenger under UK261 for a flight over 3,500 km with a 3+ hour arrival delay.
How long can I wait to claim?
UK261 claims can be brought up to 6 years after the flight date.
