They didnt sell HUY to raise funds for STN. They sold it because it didnt fit in well with their overall strategy. I dont think they were rushing to sell it, more that they were approached by T3 with an offer.
Were it not for the £45million investment at BOH then Im sure it would be the same story there. They dont need experience in operating small airports if they had no intention of operating them.
It is surely no coincidence that in the first two months under mew ownership, HUY have already secured new flights for next summer..
