What a lot of companies don't realise is that 'Business Restictive' (i.e. fixed date / time) flights are often cheaper than 'Flexible Economy'...... Particularly if booked on-line rather than through an agent.
Reecently I travelled on a Business Restrictive ticket to Madrid and back via Frankfurt - it was several hundred € cheaper than the cost of a colleague's ba-conair direct flight in LoCo Economy class squeezed into an EMB-145.
