There's no legal maximum on how long an airline can delay your flight - but the law is precise about when each delay threshold triggers compensation, care obligations, or your right to walk away with a full refund. Most passengers don't know that a 3-hour delay in Europe means €250 to €600 in their pocket, that 5 hours means the right to abandon the trip and demand a refund, or that the clock starts at arrival, not departure.
At Gyro, we file thousands of delay claims a year, and the pattern is consistent: passengers who know the exact thresholds and what evidence to capture walk away with two to three times more compensation than those who rely on the airline to do the right thing. This guide breaks down every delay scenario, every threshold, and exactly what to do at each stage of a delay.
No federal or EU law caps total delay duration. Airlines could theoretically delay a flight indefinitely. What the law does instead is escalate your rights at specific thresholds.
From our claims experience: airlines occasionally cancel delayed flights at the last minute, which actually upgrades your rights significantly. Cancellation triggers EC 261 compensation AND refund rights, where extended delay only triggers compensation. If your flight has been delayed 5+ hours and looks unlikely to ever depart, request cancellation in writing, since the refund rights that kick in on a cancelled flight are stronger than anything an extended delay gives you.
This is the single most misunderstood rule in delay compensation, and it costs passengers thousands of euros annually.
From our claims experience: passengers regularly photograph the departure board showing a long delay, then are surprised when the airline refuses their claim because the actual arrival delay was below 3 hours. Always note the actual doors-open time at destination. This is the moment that matters.
Care obligations kick in at 2 hours under EU 261 and escalate from there.
Care obligations apply regardless of cause - even if the delay was due to extraordinary circumstances that exempt the airline from compensation, they must still feed you and house you. From our claims experience: airlines frequently skip care obligations during extraordinary circumstance events (major weather, strikes), incorrectly assuming they're off the hook entirely. Receipts for meals and accommodation you paid out of pocket are reimbursable.
Yes - and your eligibility can disappear with it. Airlines sometimes recover lost time mid-flight or take routing shortcuts to arrive sooner than expected.
Yes, except in the most extreme cases. Staying home costs you both rebooking options and care benefits.
From our claims experience: leaving the airport during a delay without the airline's written agreement is one of the fastest ways to forfeit your rights. If you must leave, document the airline's confirmation by email or SMS before going.
Generally no, under US DOT rules. The exceptions are narrow but specific.
From our claims experience: US passengers often assume "American law doesn't help me with delays" and don't file anywhere. But if any segment of your trip departed the EU or was operated by an EU carrier into the EU, the full EC 261 framework applies even for US passengers. A New York-Paris-Rome trip on Air France has EC 261 protection on both legs.
Delay rates vary enormously, and choosing carriers wisely matters for high-stakes trips.

Whether you receive compensation depends on classification, but care obligations apply regardless.
From our claims experience: airlines frequently misclassify staff strikes as "operational disruptions outside our control." Cite the Court of Justice's Krüsemann ruling, which confirmed that airline-staff strikes don't qualify as extraordinary circumstances, and if the airline holds its position, escalating to the right regulator is usually what forces a reversal.
Flight delays are the most common air travel disruption and one of the most poorly understood from a passenger rights perspective. The absence of a legal maximum delay length creates the impression that airlines can simply hold passengers indefinitely with no consequences. In reality, every hour of delay triggers escalating obligations: meals at 2 hours, cash compensation at 3 hours, refund rights at 5 hours, hotel and transport at overnight.
The single most important thing to understand is that the delay clock runs at arrival, not departure. Photographing the departure board and claiming compensation for a "5-hour delay" doesn't matter if the actual arrival was only 2.5 hours late. Conversely, a flight that departs on time but arrives 4 hours late is fully eligible, even though it didn't feel particularly disrupted at the gate.
US passengers face the weakest delay framework globally and often miss that international segments of their trips may qualify under EC 261. EU/UK passengers face stronger rights but airlines that systematically refuse valid claims - particularly ultra-low-cost carriers like Wizz Air, Spirit, and Frontier. The escalation ladder works in both regions: written claims citing specific regulations, regulator complaints after refusal, then small claims court or claim service if needed.
If your flight has been delayed in the last 1 to 6 years (depending on jurisdiction), you may still be entitled to compensation. The time to file is now, before evidence quality decays and country-specific deadlines expire.
If your flight was delayed 3+ hours, you may be owed €250 to €600 under EC 261 - or potentially more under the Montreal Convention. Gyro checks your eligibility for free. You keep 100% of whatever the airline pays.
