My condolences,
sonicking
Ive cancelled a multi-pax non refundable booking, for all passengers (purchased directly from CX), when one of the passengers fell sick with COVID. This was well after COVID waivers had ended (May’23). A copy of the doctor’s covid note had been sufficient for Cx to provide a full refund. Not quite sure how things would work given Expedia is the agent, but I think calm persistence will help- try pointing to 3.2.4 of the Conditions of Carriage
