Luke:
I would contact the Travel insurance company immediately, and request a claims form. Then, fill it out and submit it. If you don't know the value of a lost article, put in the price of a replacement article, without regard for sales and so forth that one cannot wait for to replace lost items. I would not be "conservative" at all in the valuation of the lost articles, including the luggage itself, as that is the job of the adjuster ---- not you! I would get this going right away, as it sometimes takes several weeks to get a settlement.
Hope this helps,
Richard :eek:
