For those of you who have lost luggage by the airlines...
How long did you wait before starting to replace what was lost?
One one hand, I don't want to have to laundry too often, awaiting my stuff, but on the other hand, I don't want to wind up with 30 pairs of socks, underwear, another suitcase, etc. if they do find the bag.
How long before I should write it off as lost?
