Interestingly one firm of industry analysts issued a report about a year back urging BMI to segment its customer base by creating a different web sites for the cheap fares gang, while the DC site would be more tailored to those looking for business and premium fares.

Personally I tend to disagree, it's an approach that one of the Scandie airlines (SAS or Finnair, I forget which) has taken and it always bugs the hell out of me that the assumption is that leisure travellers don't look for flexible tickets and business travellers don't look for cheap tickets.
