JetBlue Testing Facial-Recognition
 

Germany uses a similar concept with their EasyPass Boarder control system. Scan your passport, step into the gate, if facial recognition identification is successful you move through the gate.

I'm definitely growing that mustache now.

(1) Australia uses this as well (for their passport control). Presumably if your face doesn't match you get diverted to deal with a human being (since computers are fallable).
(2) However, in the context they are using it, it is hard to put into words how utterly useless this is. You still need a BP (and deal with a passport check) to get through security, so for now all this seems to be to me is an unnecessary "gee whiz!" toy that has a chance of breaking and causing problems. I'll admit to being something of a luddite but this does not seem to be much more than a solution in search of a problem and it'll be fun to see what happens the first time the system breaks down and a dozen pax have already tossed their BPs (and/or when you get two passengers swearing they have seat 10C because it's stupid o'clock and one of them actually has 10D*).

*I've been this passenger once, mainly because I got mixed up as to which side C and D were one morning on an absurdly early flight out of LAX.

It's actually a "test" being done for DHS/CBP for the government to more comprehensively monitor and control the travel of persons in the US.

Delta and JetBlue seem to be in government-kiss-up mode, and this "JetBlue-testing" is but an effort by the government to enable/implement a more comprehensive surveillance/control state applicable to passengers. The government should be thankful that the airlines are such kiss-ups to governmental demands/pursuits.

Well, I, for one, am intrigued. I'm all for sci-fi-y concepts at hotels and airlines, and I'm saving up JetBlue miles to fly to Aruba anyway.
