I don't know what compensation for broken IFE in United Business. But in Raffles Class on Singapore Airlines, for an entire cabin with nonfunctioning KrisWorld, compensation is a free seat w/ functioning IFE in economy at your disposal, as well as $150 of onboard duty free. That bought a pair of Bang & Olufsen earphones, a bottle of cologne, and three jars of tiger balm. Not too shabby.
