She cancelled the flight on the 26 June when she got back from the hospital and when she went to claim on her insurance, they said that since the timing of the cancellation fell outside the policy, they wouldn't be covering her.
Goodness me this is so tricky. It seems to me she therefore should not have cancelled prior to the 28th June to be covered. 28th June being the start date of cover.
Let's say the policy starts on 1st June. She could then cancel any day in June to be covered, but she could not cancel in May. That what it seems to mean that these annual policies are about.
I guess it makes sense. Let's take her booking a holiday next year 2016, in July. But breaks her leg in June, within the annual period of the insurance. Would she be covered then I wonder.
