Other mistake: When Lisa is going through the airport to board the plane, she calls her father. She should be going to the check-in area; however, she was walking in the baggage claim area, where you return from flights. (00:05:20)
Other mistake: When the Deputy Secretary of Homeland security is on TV at the airport while everyone is waiting out the flight delay, his title is spelled wrong, as "Deputy Secretary of Homeland Securty", on the TV screen. It is corrected on the change in the shot. (00:14:38)
Other mistake: After Lisa escapes from the plane, the flight attendant picks up a phone to alert Airport security. Instead of dialling a number for the intercom, the flight attendant just frantically mashes at the phone several times never actually hitting any phone buttons whatsoever. Evidently this actress believed with all of her heart that what she was doing looked like dialling numbers. (00:57:19)
Other mistake: The FL driver license of Lisa's dad has 327 Maryland Ave and not 9321 Blossom Palm lane. It's standard for the driver license to reference the actual residence address.
Answer: These are very tech-savvy terrorists. Not only would they be watching Keefe, but also Lisa, who is integral to their assassination plot. The assassins would have been monitoring their every move, intercepting cell phone calls, hacking into the hotel's and the airline's computers, and so on. It is unknown how Jackson got a seat right next to Lisa, but as it's a late-night flight, there would likely be fewer passengers and he could have managed to be seated next to her or somehow got the airline to switch him with another passenger.
