Hi Gary,
No replies unfortunately. Plan to call the insurance company about 3 months before the trip.
Maybe able to get Taxes and Fees back from Ebookers but not the actual flight cost. If thats the case will try and get back just the flight costs and car rental from the insurance company. May help to get a doctors note nearer the time to prove you can;t fly.
Though knowing what insurance companies are like not holding out much hope.
Let me know if you have any luck
Raj
