The new owners have only been in residence for a few months which is not a long time ... beleive me!
The travel show was sponsored by LPL because that is who the organisers asked first, nothing to do with the airport.
The point about marketing is important. I think it is important to remember that the art of marketing is as much about timing as it is the content. At the moment, if BLK spent a huge amouont of money on marketing it would a better opportunity later WHEN the airport has more routes to offer ... there are many many elements at play here ... and whilst it can be frustraing form the outside, you need to give the new owners a little bit of trust and be patient.
That is my view anyway!
