Whilst not explicitly covered by the terms it wouldnt be too hard to argue that $300 for a new flight rather than the $1,000 for abandoning both flight and hotel booking is mitigation of losses and therefore would probably receive a payout.

Also, why do you need it? If for example its to meet a cruiseboat then travel insurance covering cruises does, again in the UK at least, inc costs associated with ensuring you get on your boat if the flights delayed. This normally is envisaged as an additional flight to the boats next stop but could again be a replacement original flight instead.
