This actually may be a blessing in disguise. Once you've accrued PPF level benefits in a DB scheme it may be a good idea to stop there and start contributing to a DC one instead. At least you know that pot is your money that nobody else can pinch (apart from HMRC, that is).
Many big companies with even bigger DB deficits (BT etc) will be actively looking at ways to get out of their DB pension obligations. And don't rely on the Regulator to take any sort of enforcement action against IAG either, they are utterly toothless.
As a victim of the Mantegazzas pension theft at Monarch I speak from experience.
