Sadly though this is India and there is no way Immigration are ever going to accept fault. In the short term they have rebooked all nine pax with the next available airline but we were at least hoping to get the taxes and fees back from BA since they didn't travel. Not expecting anything else from them since I think we all accept this isn't their issue ...
