SJU - ORD on 1/27/11
The TV monitor was all jacked up, giving funky colors, and making smiley smisek look green. Couldn't really watch the entertainment without getting nauseous. Couple that with a stuck open air vent blowing cold air the whole flight.
Sent a heads up email to the 1K desk, and they sent me a $350 E-cert, unsolicited. Quite a nice surprise. ^^
