Travellers who have flown with TUI, easyJet, Ryanair and other airlines could be entitled to around £1,300 in certain circumstances. This is due to a global treaty signed in 1999 and implemented in 2003.

The Montreal Convention holds airlines accountable for damages to health, flight delays, cancellations, and the loss and/or damage to any bags during your flight. This means you have the right to claim compensation for a number of eventualities.

Some of the largest claims are likely to be where luggage has been lost by an airline. According to TUI’s website: “The air carrier is liable for destruction, loss or damage to baggage up to 1,288 SDRs (approximately £1,325).

“In the case of checked baggage, it is liable even if not at fault, unless the baggage was defective. In the case of unchecked baggage the carrier is liable only if at fault.”

The maximum compensation for baggage delays is also 1,288 SDRs, as reported by the Liverpool ECHO.

Lost or damaged luggage should be reported to TUI within seven days, it said. easyJet, Ryanair and Jet2 are also governed by the convention, meaning passengers may be able to claim up to around £1,325.

easyJet’s website states: “If we lose or damage your hold luggage and you report this to us at the arrival airport, we may be liable for the loss or damage. Our liability is limited to the financial limit set out in the Montreal Convention, which is 1288 ‘Special Drawing Rights’.

“You can increase this limit to £2,500 only if you make a special declaration when checking in your luggage and pay a fee of £37.”

Ryanair says damaged bags must be reported at the arrival airport, with a claim submitted to Ryanair within seven days, while lost luggage should be reported at the arrival airport, with a claim submitted within 21 days.

Jet2’s official website offers clear instructions for passengers facing baggage issues: “If you experience any loss, damage, or delay to your baggage you must tell our team straight away. Please make sure that you complete a Property Irregularity Report (PIR) before leaving the airport, as without this document our Customer Services team may not be able to process your claim.

“You will also need to keep a copy of the completed PIR.”
