BA8754 Madrid > London City diverted to Stansted last night for 'commercial reasons'.

[PAXboy]

Rusland 17

What, exactly, would you expect BA to do?

1. Tell me why we were diverting before we took off.
2. Update me during the flight if the problem at destination had not been fixed.
3. Have a coach ready and waiting on nearest possible (land side) bus stand, with ground staff displaying information and directions. This to be announced to pax before disembarkation.
4. Update the electronic signs at LCY/STN/the web site for all meeters and greeters.
5. Trigger standard e-mails to all listed on pax profile, as some might be families or work colleagues and they might get the message whilst flight in progress.

Easy as pie for a large carrier that has flights diverted every day for all sorts of different reasons. There are (should be?) standard automated process' for this, that only require to be kicked off. It's called a SOP.
