Could the ILT give an example of ‘all reasonable measures’ mentioned in the policy?

The Human Environment and Transport Inspectorate (ILT) provides the airlines a format/form to use to appeal for justification (‘force majeure’), with guidance on how to prove the cause and what evidence is required. These formats will be published on this website.

'All reasonable measures' are mentioned in point 50 of the Policy regarding misuse of slots.
