Another instance of a complaint that's like to end in compensation within the UK or EU is a complaint to KLM about a flight they cancelled less than 2 weeks before the scheduled departure date.

Aside from KLM delayed or cancelled flight compensation, you may also lodge a complaint requesting a full refund for a cancelled flight, or reimbursement for expenses incurred as a result of damaged luggage.
