No engineering has ever been made on the a/c positioned into Cardiff other than when it went tech, The reports in the news forgets to mention that for a month after Christmas,the a/c did not position to CWL because of either BMED moving offices or ATC which meant that no traffic were to take off unless it had to.
During the time of the Fog were most UK airport were effected it was sent out to do a rescue mission to collect bags that had been left behind.
BMED has slots that will be lost if they don't use them, which they wanted to keep. What else can they do (except to use a smaller a/c on lease), i'm not sure if it would cost them more to do so.
