Listen to calming music. Most airlines now offer a new wave or serene audio channel, enhanced by breathing techniques and meditation exercises.

Other airline stress reducers: Virgin Atlantic's head and neck massages, and manicures; British Airways' eye compresses, facial sprays and their radically new seats that recline into beds, complete with sheets and pajamas.

Tune out the surrounding environment and passengers. Focus inward, read or listen to music. Bring your own headphones and portable tape player. Use eye shades and earplugs to help create a cocoon effect. 

Ask for some pillows. Pillows provide physical and emotional comfort.

There are relaxation tapes available (sometimes you can find them in the airport gift shops) that are specifically designed for the air traveler.

Remember the second you feel any tension or anxiety, use deep breathing and pleasant imagery to calm yourself.
