Many years ago I walked out of a Miami Airbus A340 course on Day 2 after Virgin Atlantic unilaterally downgraded my course (of 6) from First Officer to Second Officer. I can’t remember if I was bonded or not but, when I said I was taking Virgin Atlantic to Court for breach of contract, they agreed to let me keep the 6,000 US dollar training float and call it quits. Never regretted my decision, it took one of my course mate 7 years to get his Command there as a result the downgrade (lost it though after 9/11).
