Watching from my armchair
...it seems to me that bmibaby are a total shambles.
They opened Manchester base, expanded it, and have now closed it.
They opened Teesside then closed it, despite having a loco monopoly
They opened Cardiff and have now closed it, despite having a Loco monopoly
They have even fluctuated their committment to Birmingham
There have been a large number of destination changes.
Their fleet is static, and pretty elderly.
Due to fleet type they have not entered the main winter market ie Canaries.
Their prices are not very competitive
Their 'add-ons' are very costly
A website redesign rendered their website difficult to use
The new routes they have chosen look difficult to make money on due to competition from much stronger airlines
In short, they are too small to compete, they have inappropriate equipment and an inconsistent stategy. I would not invest my money in them or even to fly with them, so I'm out. Sorry.
