Well they told me I could be refunded but it was for a fraction of the overall ticket price. They told me it would be better if I did not want to rebook with another airline (to get myself home) to book an alternative route with them which would still get me to the UK.
Spent several hundred pounds calling to find out precisely how I would be then transported to my final destination, i.e. where I flew from, which was hundreds of miles away from where they were proposing to fly me to. In the final call an agent told me I was not entitled to either a reroute OR a refund and that the ticket was now invalid.
So paid for my own flight home. Now found out that agent gave me completely the wrong information.
So just trying to find out precisely what laws or conditions of carriage the agent should have known about.
