Each of these is a refusal this regime lets a counterparty attempt, paired with the answer to it. Reading them before you write is worth more than any amount of polish on the letter itself.
The airline answers with a European figure
high likelihoodA carrier familiar with EU261 quotes a EUR 250-600 tariff, or says no compensation is due at all because the delay was under three hours.
What answers it
The Saudi scheme is not a distance tariff. Denied boarding pays 200% of the unused ticket value plus a refund; a cancellation notified under 24 hours out pays 150%; a delay of three to six hours pays 50 SDR and beyond six hours 150 SDR. On an expensive ticket the percentage limbs are worth far more than any European band.

Silence about the Article 17 care penalties
high likelihoodThe carrier settles the disruption claim and says nothing about the fixed sums for failing to provide refreshments, a meal or a hotel.
What answers it
Article 17 makes those sums payable in their own right and in addition. Claim them explicitly, say what you were not given and when, and cite the article. They are small individually and they are the part of the regulation carriers most reliably overlook.

We put you on another flight
high likelihoodFor denied boarding the carrier says compensation is waived because it rebooked you.
What answers it
The waiver applies only where the alternative flight departs within two hours of the original scheduled departure. Check the scheduled departure of the replacement, not its arrival, and not when you were told about it.
