No it can't.
Surely it can't.
But...... if it's true it would be a big error of judgement. I know its only a handful of flights but SEN has no problem with filling routes to sunshine resorts so they would have succeeded. More importantly, it's British Airways for goodness sake. Having that brand at SEN, even if only for a handful of flights, would give a real boost to SEN's reputation.
But SEN's management must know that and wouldn't have allowed their company policy (if that's what it was) to be so inflexible that they let this opportunity slip through their fingers.
