Most are familiar with the legal precept of posted sign not necessarily relieving establishment of punitive damages litigation.
Let me be more specific with this example of a damaged luggage posting at the airport in Roswell,NM. Whoever posted this sign could not have consulted with competent attorney. The sign reads: Luggage is designed to protect its contents. As such, American Airlines assumes no liability for minor damage such as scratches, scuffs, stains, dents, cuts and dirt resulting normal wear and tear
American Airlines assumes no responsibility for damage to or loss of protruding baggage parts such as wheels, straps, pockets, pull handles, hangar hook or other items attached to baggage.
What this signage does is effectively give baggage handlers carte blanche discretion to roughly throw your baggage around and not suffer any consequences for damages. American Airlines has no authority to define the function of luggage to suit their needs. Many travelers purchase stylish luggage and carry on bags and do not have to tolerate arbitrary decrees, which are not legally supported, about what they can get away with when handling your luggage!
This is not an attack on baggage handlers who are in a big hurry to load the plane, but given the high prices of airline tickets, the airline industry has a duty to handle suit cases and other luggage items with enough care to not rip off the wheels and top handles!
