Under EC 261/2004, if a flight is delayed the airline may be obliged, depending on the length of delay and the length of the flight, to provide the following: o Free meal and refreshments o Free telephone call o Free hotel accommodation if departure is delayed until the next day o Free transport between airport and accommodation The length of delay which gives rise to entitlements under the regulation ranges from a 2 hour delay on shorter flights, up to a delay of at least 4 hours on longer flights. Where the delay is longer than 5 hours, the passenger is entitled to be reimbursed. (Under the Montreal Convention there is also provision for air passengers to seek compensation from the airline carrier for delays. It states that if a passenger is delayed financial compensation must be offered. However the carrier is not liable if it can show that it took all reasonable measures to avoid the delay or it was impossible to do so.)
