According to news reports, this holiday season will involve a record 51 million people coming in and out of U.S. airports. And it will seem that most of them are in line ahead of you at check-in.

Also, before you head for the airport, be sure you’re up on all in-force regulations about security, including what’s OK and what’s not allowed in your carry-ons. Therefore, when waiting for your flight to be called, the best attitude is to grin and bear it. Even if you have to bare something personal in the check-in security line.
