Used them for our first trip 5 years ago. It was fine, plenty of leg room (compared with package!!). Free drinks, good food, ice creams, no seat back TV's but it was a long time ago. All on time but our connection at NY was very quick - we got a ride from the little guy who normally transports disabled folk!
Onward flight was overbooked (quite par for the course) and they were offering a O/N stay in NYC plus $??. As it was our first trip and our kids were desperate to get to disney we didn't take them up on it, but plenty did so everyone who wanted on got on the flight in the end.
