Air travelers should prepare for some changes this holiday season.
Planes will be more packed as airlines cut capacity.
Also children 12 and under can leave their shoes on when going through security. The policy change became official in September.
And in some cases children can be sent through detectors or image machines multiple times, instead of getting a pat-down.
Be mindful of increased fees for checked bags at most airlines. Don't expect a discount for prepaying for checked bags online.
