To the best of my knowledge (and having done a bit of googling to check that I'm not spouting even more rubbish than usual), the only 'consequential loss' that's sometime covered by travel insurance is that relating to the collapse of an airline (or other carrier).
Nobody seems prepared to offer cover for other types of consequential loss. which is probably understandable as some consequential loss claims could be both massive and complex. (e.g. a company director who claims that his business lost millions of pounds through him not getting to a meeting on time)
(Things are somewhat complicated too by the fact that the Financial Services Authority ruled in 2008 that insurers shouldn't use the term 'consequential loss' in their contracts at all but should, instead, specify exactly what types of loss are, or aren't, covered).
Although, since 1 October 2016 (under the provisions of the Consumer Rights Act) it's now possible to claim for consequential losses against most other types of carrier (e.g. rail companies and coach operators), there's no such entitlement when it comes to air travel.
So I strongly suspect that you're seeking something which simply doesn't exist. (Sorry!)
