It's free for browsing, then you pay a fee for streaming. We'll see if that sticks in the long run, but for now, as noted in their Investor Day presentation, there is a revenue stream from advertising partners.
I think this is a huge knee-jerk reaction amongst the media and public for something that is evidently not as valuable as people think.The airline will still be unique - customers will still have 1.5 inches + more legroom than any other carrier in coach. Snacks, drinks, etc. will still be free. And a checked bag will be fee if you want to pay a slight premium over the a la carte fare. At this junction, it's very clear on the revenue front that JetBlue is hardly being rewarded for having extra leg room.
The airline needs to evolve, and to be quite clear, it needs to evolve in 2 aspects: 1st, cost containment, 2nd revenue generation. Cost containment is structural, and the fault of management for letting things escalate quicker than anticipated. But the carrier also needs to evolve to remain competitive in the revenue market place. If I recall correctly, almost every domestic carrier has decreased seat pitch in the past 5 years, cramming more seats into the airplane. What doe that mean? That means that when Delta and JetBlue both fly NYC-Florida, and Delta's crammed 12 more seats into their A320, their breakeven fare in the market just encroached upon (and possibly surpassed) JetBlue's. Generally, the public has spoken - the price point will matter more than the legroom.
If people don't like this evolution, I can assure you the alternatives would be much, much worse. If there were no changes made, and you look at JetBlue's valuation prior to rumors floating of these changes back in May, the carrier would have been an exceptionally cheap acquisition target. One of the (if not the) cheapest in the industry, from a stock multiple, as a matter of fact. So, you have to evolve if you want to say on the map. I won't even get into how "every other carrier" has elected to shed costs to remain competitive - we all know how that story goes.
