I just wondered Ron and Sue, have you looked into transferring the flights to another date or refunds? I ask this because I am in a similar position but with Ryan Air.
I was supposed to be going 6-18th August but no longer able to (have booked for October instead now)
I haven't yet looked into whether you can be credited the amount back to use at a later date or whether I'll just lose out - I keep meaning to email them but haven't got round to it, keep putting it off :-/
