Free eligibility check and a fixed €39 fee only when we recover money. ## London to Istanbul flight delay or cancellation: what are your rights? London to Istanbul is a major corridor linking Heathrow, Gatwick and Stansted with Istanbul Airport and Sabiha Gökçen. The great-circle distance is approximately 2,500 km, which places the route in the middle compensation band. The trigger is an arrival at your final destination three or more hours late, a cancellation announced with less than fourteen days' notice, or involuntary denied boarding. Because Turkey is outside the EU and the UK, the direction of travel and the operating airline decide whether you are protected at all — this route has one of the clearest coverage gaps of any city pair we handle. ## How much you could be owed Between 1,500 and 3,500 km, so the middle band: £350 per passenger under UK261 for flights departing London, or €400 under EU261 where that regulation is engaged. The Article 7(2) halving applies only above 3,500 km and does not arise here. If Istanbul was a connecting point on a single booking — onwards to Asia or the Middle East, for example — eligibility is measured at your final destination and the band is calculated to that point, which can move the claim higher. ## Why is the Istanbul to London return often not covered? Departing London, UK261 covers every operating airline, Turkish carriers included, because the departure is from a UK airport. The return is where claims fail: an Istanbul to London flight is covered only when the operating airline is a UK or EU/EEA carrier. Turkish Airlines and Pegasus flying into London are not covered by UK261 or EU261, because neither is a UK or European carrier. British Airways flying the identical inbound route is covered. Same city pair, same delay, a different outcome depending on whose aircraft you are on — check the operating carrier on your return leg before assuming anything. ## Airlines flying this route The corridor is typically served by British Airways, Turkish Airlines and Pegasus, with the mix depending on the London and Istanbul airports concerned. Codeshares exist, and the regulation attaches to the airline that actually operated the flight, so the boarding pass matters more than the booking confirmation. ## How to claim Send the flight number and date and we confirm the direction, the operating carrier and whether the flight is covered before anything else. Where it is, we calculate the band and test any defence: late inbound aircraft, crew duty limits, technical faults and the airline's own crew strikes are within its control, while severe weather, air traffic control restrictions and security incidents can be extraordinary circumstances — which the airline must prove with evidence. The eligibility check is free. If we recover your compensation we charge a fixed €39 success fee — the same whether you're owed €250 or €600. No win, no fee. ## How do you claim London to Istanbul flight delay compensation? Start with the flight itself. Our [free flight check](/claim) reads the recorded times for your London to Istanbul flight and tells you which band it falls in, in about two minutes. A London to Istanbul compensation claim turns on two things: the arrival time, and the reason the airline gives. For a late arrival, read the [flight delay compensation guide](/flight-delay-compensation). For a flight that never flew, read the [cancellation compensation guide](/flight-cancellation-compensation). It covers London to Istanbul cancellation compensation too. Has the airline said no? The [case law summary](/passenger-rights/case-law) sets out what the courts make of the usual excuses. ## Frequently asked questions ### Is my Turkish Airlines flight from London covered? Yes. A London departure falls under UK261 whatever airline operates it, including Turkish carriers, so the £350 band applies for an arrival three or more hours late. ### Can I claim for my Istanbul to London return on Turkish Airlines or Pegasus? No. Arrivals into the UK are protected only when the operating airline is a UK or EU/EEA carrier, and Turkish carriers are neither. The same inbound flight on British Airways would be covered. ### How much is a delayed London to Istanbul flight worth? Approximately 2,500 km places the route in the middle band: £350 per passenger under UK261, or €400 where EU261 applies, subject to the airline not proving extraordinary circumstances. ## Sources - https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A32004R0261 - https://www.caa.co.uk/passengers/resolving-travel-problems/delays-and-cancellations/ - https://curia.europa.eu/juris/liste.jsf?num=C-402/07 - https://curia.europa.eu/juris/liste.jsf?num=C-549/07 - https://curia.europa.eu/juris/liste.jsf?num=C-195/17 - https://curia.europa.eu/juris/liste.jsf?num=C-452/13 Read the full page with the claim check at https://flightcompensations.com/routes/london-istanbul
