I've recently had to reroute some of my next trip. I had a week in Tunisia planned, but decided to avoid right now while the situation there is uncertain as to whether the local government can maintain security over further direct attacks at tourists. Given i'm still going to Jordan (right next to a warzone), my friend was more concerned about Tunisia, mostly due to the fact that the attack was directed at tourists. So we started the process of changing flights etc. I called the insurance company thinking i might get something, but alas no, as soon as terrorism is involved the policy becomes absolutely useless, regardless of where you go or if there was any risk or terrorism before hand. This was with cover-more, so I've blacklisted using them ever again. But TID has similar clauses as did the other two I checked at the time. I'm not surprised by this at all, I'm fully aware of insurance having clauses to get out of things that may cost them a lot of money.
Many people I know were shocked, that for example if a tourist was involved in the Lindt Cafe siege in Sydney and had travel insurance, they'd have got nothing with most of them, mostly because it was declared a terrorist incident.
I did look at the CC insurance on my Woolworths CC. Similar clause regarding cancellation cover. Less obvious if you'd already commenced travel and is also limited to 30 days maximum. Good for a week in Fiji or SE Asia, but not much more IMO.
In the end It cost a lot to change the AMM-TUN and TUN-CMN leg of my trip. I've ended up with AMM-FRA-SOF and SOF-DOH-CMN which is a long way round to get to Casablanca with a week in Bulgaria. The good bit is I got a cheap Business class fair on Qatar air, admittedly on aircraft with their older business class seat, but better than a cramped economy seat for a long overnight flight and connection (by comparison Iberia and BA were more expensive for economy than the Qatar business class fare). I also learnt a bit about changes to airfares, I kind of assumed a change like Amman to Athens or Cyprus would be cheap, but they were $900 vs the $300 to go to Frankfurt!
I think we all know the moral of the story though, read the PDS first!
