Ethiopian Airlines - delayed luggage - no compensation

We travelled to Europe on Ethiopian Airlines via Addis Ababa during December 2025. Upon arrival at Rome, Fiumicino Airport, my partner's bag did not arrive with the flight as expected. After completing the required missing luggage forms, the luggage where eventually found and sent to Rome, Fiumicino Airport. By that time we were already in Venice and the delayed luggage was rerouted to Marco Polo Airport. Seven days later and almost $450 out of pocket for essentials, we were re-united with our bag. We had to collect the luggage ourselves as we were travelling to Croatia the following morning. After enquiring about the reimbur*****t of delayed luggage, we were informed that Ethiopian Airlines only pay $100 per passenger in economy class for delayed luggage. I found this unacceptable as per their own terms and conditions for delayed luggage, they are part of the Montreal Convention, and under these conditions, airlines are liable for delayed baggage on international flights, requiring them to compensate passengers for "reasonable" interim expenses (e.g., toiletries, clothing) up to a maximum limit of approximately 1,288 Special Drawing Rights (SDR) – roughly €1,600-€1,900 or $2,000+ USD – per passenger, not per bag. Claims must be submitted in writing within 21 days of receiving the baggage We had to settle for $100 or nothing at all. NOT FAIR Now, some three months later, we are still waiting for the $100 refund with no feedback from Customer Service and/or their accounts department I find their lack of service and their ethical conduct disgraceful. UNACCEPTABLE
