International Flight Delay: When Montreal Convention Beats EU261

Montreal Convention vs EU261 flight delay claims involve two parallel international frameworks with different mechanisms. EU261 is a fixed cash compensation regime: EUR 250, 400, or EUR 600 depending on flight distance, paid regardless of your actual loss. The Montreal Convention is a documented-loss recovery regime: you claim the actual financial loss caused by the delay, up to the convention's per-passenger liability limit of about USD 7,300 (currently 6,303 SDR, the IMF's Special Drawing Rights unit). The two frameworks coexist and in most cases you can claim under both. The question is which to lead with and where each beats the other.

EU261 wins on simplicity and small claims. Montreal Convention wins on large documented losses, baggage, and non-EU routes. The two are not mutually exclusive on EU-covered routes.

Article 19 of the Montreal Convention holds the carrier liable for damage caused by delay in the carriage by air of passengers, baggage, or cargo, unless the carrier proves it took all reasonable measures to avoid the damage. The convention applies to international carriage between any two states that have ratified the convention (which includes virtually every country with commercial aviation). Damage means actual proven financial loss: missed connections that required new tickets, hotel costs incurred because of the delay, meals during the delay, lost wages from missed work, prepaid hotels not used, and similar. The per-passenger cap is currently 6,303 SDR (about USD 7,300 in late 2025 dollars).

EU Regulation 261/2004 provides fixed cash compensation for flights departing EU airports (any carrier) and EU-carrier flights arriving at EU airports. Compensation is EUR 250 for distances up to 1,500 km, EUR 400 for 1,500 to 3,500 km, and EUR 600 for over 3,500 km. The cash compensation is paid regardless of actual loss: no documentation of damage is required. Article 9 of EU261 also requires the airline to provide meals, hotel, and ground transport during the wait, and Article 8 provides a refund or rebooking right. See EU261 explained: complete guide and EU261 calculator: exact euro amount by distance for the full compensation framework.

  Large documented losses: A delay that causes USD 5,000 in actual losses (missed cruise, prepaid hotel, business loss) is recoverable under Montreal up to USD 7,300. EU261 caps cash compensation at EUR 600, regardless of actual loss.

• ›

  Baggage delay: The Montreal Convention's separate baggage liability (1,288 SDR, about USD 1,500) is the primary route for baggage compensation. EU261 has no baggage delay payout.

• ›

  Non-EU routes: A Tokyo-to-Sydney delay on Qantas is not covered by EU261. Montreal applies because both Japan and Australia are Convention states.

• ›

  EU-departing flights to non-EU destinations: A Paris-to-Tokyo flight delay is covered by both. If your loss exceeds EUR 600, file under both and stack.

• ›

  US-departing flights to international destinations: A JFK-to-London flight is not covered by EU261 (US-departing). Montreal applies on the international carriage.

EU261 wins on simplicity and small-loss claims. The cash compensation is fixed and paid regardless of actual loss. A 4-hour delay on a Paris-to-Madrid flight triggers EUR 250 cash, even if you suffered no out-of-pocket cost. Under Montreal, you would have to prove actual damage, and small inconveniences are unlikely to be reimbursed. EU261 also has a stronger duty-of-care framework: meals, hotel, and ground transport are mandatory, where Montreal requires you to incur and document the costs first. For most passengers on most EU-covered flights, EU261 is faster and easier. Montreal is a top-up when EU261 caps out.

On EU-covered international routes, you can claim under both frameworks. EU261 provides the fixed cash compensation regardless of loss. Montreal Convention provides the documented loss recovery beyond what EU261 covers. The two are not mutually exclusive. The total recovery is the EU261 fixed amount plus the Montreal documented loss minus any double-counted damages. For example, if EU261 pays EUR 600 and your actual loss was USD 5,000, you collect EUR 600 from EU261 plus USD 5,000 from Montreal (capped at USD 7,300 per passenger). The strategy is to file both claims simultaneously and let the airline allocate.

Stack EU261 and Montreal claims on EU-covered international routes. They are not mutually exclusive. The airline often pays the EU261 amount quickly and disputes the Montreal claim, which is the right outcome for most passengers.

Airlines almost always lead with EU261 on EU-covered flights because the cash compensation is capped. They rarely volunteer the Montreal Convention option, especially for passengers with documented losses exceeding EUR 600. If you have receipts for missed connections, prepaid hotels, business losses, or medical costs caused by the delay, file a Montreal Convention claim in addition to the EU261 claim. The airline will sometimes settle the Montreal claim quickly to avoid the discovery cost of contesting it. See airlines avoid paying EU261 compensation for related deflection tactics.

1. 1

   Confirm whether the route is covered by EU261 (departing EU airport, or EU-carrier arriving at EU airport).

2. 2

   If yes: file the EU261 claim first. The compensation is fixed and easier to recover.

3. 3

   Document all out-of-pocket losses: receipts for missed connections, hotels, meals, ground transport, lost wages, missed prepaid bookings.

4. 4

   If documented losses exceed EUR 600: file a parallel Montreal Convention claim citing Article 19.

5. 5

   If the route is not covered by EU261: file under Montreal Convention exclusively.

6. 6

   If the airline disputes the Montreal claim citing 'all reasonable measures': request the operational documentation under data-access rights (GDPR for EU carriers).

7. 7

   If the airline ignores the Montreal claim: escalate to the national enforcement body of the carrier's home state, then to small claims court if necessary.
