Gosh, so people still call the airport?
Some people still call the airport? Or the airline? Hmm. I thought this was a credibility goof; surely her kids have Internet and she could have checked his flight status online. EVEN IF she'd done that first and they'd showed her on the computer, THEN making the phone call, I think it would have been more current. I think the screenplay writer who rewrote this from the book messed up big time.
Obviously, JMO. I enjoyed the movie otherwise - it was OK.
