UK Departure Taxes Pinching BA

British Airways must be feeling the pinch from the UK's crazy high departure taxes.  They have started to organize political action to repeal the tax burden with their (and 30 other travel related organizations) website: afairtaxonflying.org/.  They even emailed international Executive Club members to spread the word.  I think they have a valid complaint because they are being priced out of the long haul connection market and must be hurting. I know I'm avoiding London stop overs if possible.
