Asprou's have been in Ireland since the sale of their tour company to Airtours, running a small aviation leasing company called European Capital (nothing to do with European Aviation) which is the lessor of a couple of B737-200's...
Seems a bit unlikely if it is an IT airline since this years programmes are done and dusted and Tour Operators now working on 2002/3 programmes.
Could be someone on an ad hoc/acmi type operation, there is certainly a need for capacity in CWL/BRS in the Summer months but would need a more lucrative home in the Winter.
