Cardiff does indeed have a strong charter traffic.
In 2006 CAA stats show BRS handled 1,374,281 terminal charter pax and CWL handled 1,057,674. Both airports also saw a small number of transit charter pax (around 11,000 each).
From the figures, more than half of CWLs PAX were on charter flights, while less than 1 in 5 BRS PAX were on charters.
M.V. Info came from a reliable source who back up the the present TCX/MYT operation at Brs, they say they are gearing up for 2nd a/c next summer with possibility of 3rd FCA to cover Tui 757 withdrawl. was not saying Cwl base gone, but just adding to the Myt thread at Cwl, make of it as you will, and lets not forget this is a rumour network, not a breaking news network.
Like you say just a rumour, not definate for two aircraft next year. With the airline joint, downsizing. I doubt you'd see much expansion. And FCA wouldnt have enough aircraft for an extra BRS one.
