In summary Apple will replace at no charge hinges of some MacBook Air, if you experience the following problems:

Symptoms

Learn what you can do if you experience one or more of these issues with the hinges on your MacBook Air.

• Unable to close lid completely.
• Broken or cracked plastic near one or both of the hinges.
• More than one inch (2.54cm) of free play while opening or closing the lid.
• Lid falls freely into closed position from a 30-degree open position. (From a closed position, open the lid approximately 30 degrees and let go.)

Resolution

You can take your MacBook Air to an Apple-Authorized Service Provider or Apple Retail Store for evaluation and repair if necessary, even if your product is out of warranty. 

If you previously paid for a repair for hinge-related issues that were not caused by accidental damage, you may be eligible for a refund.

It reminds me the video of a user who destroyed his MacBook Air with a hammer because the hinge had a problem and preferred to purchase a PC notebook... get the lesson, never act without thinking twice ... or Think different.
