I don't think there is anything such as free. I think that if you fly on another airline you're always going to pay at least 10% of the full published fare for that cabin. I could be wrong and others can correct me however I was recently speaking with some people with infants (6 - 9 months old), they were redeeming award tickets, they had to pay 10% of the published fare for the infant, a couple agents said that its similar to what airline employees pay to fly another carrier and what people on buddy passes pay. Between having to pay the portion of the fair AND travel Space Available you have to ask yourself whether that perk alone carries enough weight, particularly if the opportunity cost is a job with some travel which earns frequent flyer miles.

As jetBlue grows, how long do you think it will be before the New York headquarters moves to Orlando or some other lower cost locale? jetBlue has to compete with US Airways on price and that is no small feat. There is a story in today's Arizona Republic, US Airways has replaced motorized baggage tugs in Phoenix with "rickshaws," the employees get exercise and US Airways (most importantly) saves money. US Airways has contracts with the very lowest cost regional carriers to fly the most dreadful old turboprops in some markets. For the consumer who is looking at price first and everything else second, US Airways takes the customer. This is what jetBlue is up against. New York is an expensive town, I wouldn't be surprised if the airline moves to Orlando. TWA moved from New York to St. Louis, American moved from New York to Dallas. I don't want to live in Orlando.
