say delayed dive gear luggage and a charter dive vessel / resort, in which a key part of your gear is delayed a day or two due to being mis-handled by the airline, I think that most live-aboards / dive resorts would lend you the needed gear free of charge until your luggage arrived, as they want to provide the type of experience that would result in repeat business / good customer service ratings.
That is/was my way of thinking as well. Why does that not apply to a daily dive Op?
