The overwhelming majority of my business travel is intra-Europe. bmi doesn't really have a comprehensive network, and they're doing a good job of making themselves unattractive to business travellers (see the threads in the BD forum about the transformation into a 'modular airline'). As for using LH, the BA nonstops from London are frequently better in terms of timing (easier to change on the day of travel; allow me to minimize travel time), cost (lower fees expensed to my client), and service.
