I'm not sure of the delayed deliverence of GECOD, but i do know that due to delayed deliverence of Dash8 that the planned capacity increase for CWL flights is put off for another 2 weeks or so.
According to Jethro's website the Aer Aerann leases are until end of October. I hope they don't plan keeping it on the BE1431/BE1432 until that date as CDG can't grasp the concept of and ATR operating on a lease for BE and is causing major probs at Cardiff regarding the transits.
