I saw that as well. Too bad my reservations are in F, I'd be tempted to get an upgrade (or downgrade) into the cockpit hehehe.

That DOB field (or 3 extra input fields) was plain nuisance, perhaps some people accounts were being hijacked and used. In reality I don't see it adding any real security benefit, since if you were able to grab/sniff on a keyboard's input you could get all the fields regardless. Too much security, my net bank does not even require all these extra bits.
