Sue I know its a week before you want to come back but Fly T/C have flights on Mon 22 Aug for 173 Euros.
I would be tempted to sit tight for a week or so. After 2 weeks of H4U going bust most passengers will be home and you may find that things settle down price wise. At the moment the airlines are doing what they do best. Cashing in on peoples misfortune.
Beware when booking 1 ways from T/C I booked some last week, they were priced in Euros. When I came to pay it gave me a choice of paying in £864 or 944 Euros. After a quick dabble on an online currency converter I found that 944 Euros was only about £835 so I paid in Euros.
On my statement Barclaycard have charged me £23 conversion commission [

I Should have paid with my Nationwide Visa.
