Airports aren't very merry during the holiday season. And there's not a lot you can do to change that. You can't change the FAA and all their rules about liquids and shoes. You can't make the security line shorter, and you can't make the plane depart any faster.
What you can do, is pack carefully and know what to expect.
Unless you enjoy walking barefoot on dirty floors, throwing away expensive liquid items and being yelled at by strangers, you want to think before you pack your carry-on bag.
Cram your checked luggage with full-size shampoo bottles and nail scissors, but don't put them in your carry-on. Any bags or purses that you're carrying onto the plane must follow the 3-1-1 rule. Bottles of liquid products (shampoo, lotion, hand sanitizer, makeup, perfume) can't contain more than 3.2 ounces of fluid, all liquid bottles must fit into one quart-size zip-top plastic bag and only one such plastic bag is allowed per person. Bags are available at the check-point. Do NOT test this rule. The security folks will make you throw away your $50 bottle of perfume. Crying and begging will not help. Sharp objects are a no-no for carry-ons. Anything that could be considered a weapon needs to be placed in checked baggage.
What else can you expect at the security check-point? The worst, in my opinion, is the shoe issue. You will have to take off your shoes and place them in a plastic bin. Wear socks (without holes). You don't want your bare feet touching that floor.
You will also have to take your laptop out of its bag and place it in its own plastic bin. You will have to remove your jacket or zip-up sweater, so don't wear a dirty undershirt.
You can't take open soda or water bottles past security, so drink up in line. You also can't take unopened soda bottles that exceed the aforementioned liquid requirement.
There are many more rules which you can find at your airline's Web site or here.
