The other point that I should add is that I have another (in fact, many other) LHR/BHD bookings, in Clue Europe, for future dates. That's my regular commute and when I can, I book long in advance, often getting fairly low CE fares. So when BA staff asserted that they could not book me onto EI or Flybe, nor could they book me on BA's own LHR/BHD flight (which had availability but is not available for public sale), I asked if they could simply change the date on any of my future LHR/BHD bookings to today. BA staff then called ticketing, gave one of those PNRs to ticketing, and BA staff then told me that they could indeed reissue one of my other future bookings to put me on today's BA LHR/BHD at a cost to me of around £281 (comprising change fee and difference in fare) but could not do the invol change to which I was entitled, onto the same BA LHR/BHD today, as that flight was not available for public sale. Can there be any greater evidence of sheer profiteering on the part of BA?
