We can’t give you advice on how to navigate a TSA security line, other than to say take a deep breath and be patient ( especially in Atlanta). But the American Chiropractic Association has pointed out that a long flight can play havoc with tightened muscles and restricted blood flow. When flying, here are some things to remember.

•  Check all bags heavier than 10 percent of your body weight.

•  When putting bags in an overhead compartment, stand directly in front of it so you don’t have to twist your spine while lifting.

•  When stowing bags under the seat, sit in your seat and gently guide the bag under the seat in front of you. Don’t force them in with jerking motions of your arms and legs. That is a good way to strain a muscle and make for an uncomfortable flight.

• Vary your position regularly to improve circulation and avoid cramps in the legs. Massage your legs periodically. And when the captain says it’s okay to move about the cabin, take him up on the offer. The stretching of the legs will feel good.

• Don’t sit directly under an air vent. The draft can increase tension in your neck and shoulder muscles.

• Treat yourself to a chiropractic treatment after returning from a long flight.
