Here's a short discussion from a planefag:
Are you sure that's Apple's HQ? The road signs are international, and traffic drives on the left side. The round building may be in Cuppertino, but the photo containing the Apple logo is not in the USA.
The aircraft in the photos is on an approach, slowly descending. An aircraft on departure would have a much higher nose-up attitude. Since the landing gear has not been extended in the first photo, the aircraft is farther than 5 miles out, and more than 1,500 feet above ground level (AGL). The landing gear is usually, but not always, extended at the glide slope intercept point. This is the point where the aircraft starts its final descent to landing. It is also the point where the flaps are extended another notch or two (not to full flaps yet) and the gear is extended. In the second photo, the gear doors are open which indicates that the landing gear is in the process of being extended. This puts the aircraft about 4 to 5 miles from the runway threshold.
Both the subject plane and the observer's plane are in fairly close proximity (about 1 mile separation) and eludes that the airport has at least two parallel runways in operation. This is something to look for when trying to identify the airport. The direction of the approach would indicate which runway is being used. If you know which runway is being used, that a) helps determine which airport is being used, and it also eludes to the wind direction. Looking for historical winds at airports (METAR) may provide a clue to the arrival time, and thus to the exact Jet Blue flight number. With a flight number, one can determine the origination point.
Try to match the background in the second photo to terrain at a candidate airport. Note in this photo that the subject aircraft is both behind and below the observer. This would indicate that it has slowed down more than the observer aircraft. This could mean that the threshold for the right runway is offset (and closer) than the left runway.
