Certainly looks that way. No statement about the others so guess they remain in place - for now.
I'm wondering who will be the first to correct the glaring historical error on the Flybe Facebook page. Claiming the Jersey Airlines Heron as part of the Flybe heritage just because Flybe was once called Jersey European is pushing it, as I'm sure any ex Morton/BUIA/BIA people can verify. There's no lineage at all!
