Query: Weaker caper novel with a glaring error

This one was an okay airport read, but the most cursory bit of research would have shown that Canadian airspace was also shut down after 9/11. Archer's heroine would have been wasting her time driving to Canada to catch a flight. I usually hang onto hardbacks to donate to a library, but this one was left behind in the hotel without regret.
