None of these stories top my brother's best downgrade ever... it was about 8 years ago, SFO - LHR and he got bumped out of his business class upgrade at the last minute. Gate agent was most apologetic and give him 17A (777). He wanders back, grumbling all the way.

17B ended up marrying him 18 months later.

They flew to London for their honeymoon and requested 17 A & B both ways...
