I do feel for the OP as we lost a bag on a flight from UK to Sydney (change in Singapore). We had two days in Sydney pre cruise, but the bag did not turn up in time! It was my husband's case and we had to shop in Sydney for everything! We also had most of our toiletries in the case and some shoes of mine. It was a nightmare and cost a small fortune. The checked case was found, but half way through the cruise when we were in Auckland. They said they would fly it out, but that could have been a bigger headache and we agreed to collect it at Sydney on our return. When we flew back, we collected the lost bag, but our luggage weight then exceeded the maximum weight due to the extra clothes and small case we had to buy, although the airline in question waived that fee. I kept all receipts for the purchased items and we had not been greedy, but purchased only the items to get my husband through the cruise and dressed in accordance with the guidelines of evening attire. At Sydney airport, we were told we would have to claim on our insurance. I informed the lady with whom I spoke that our insurance Company had not lost the case and why should they pay! I made the claim on my return and we were reimbursed every penny - they were absolutely marvellous and did not quibble. I would rather not have lost the bag however. I think we will go down the Air Tag route and we also cross pack!
