well origionall the morning rotations of the GLA-CWL-CDG-CWL-GLA was to operate on a RE wet leased a/c. Last week it was on a German 146. I have been informed it's due to delayed deliverance of Dash 8's.
This could also mean that an E145 is being used on another route for this reason.
We also have an E195 coming in tomorrow to operate the BE285/286 tomorrow and the morning BE281/282 ahs been non-op for a while on certain days.
