Our luggage was checked on a United flight from Denver to DFW. When it was retrieved one suitcase was torn. I tried to file a claim and was told because the tear was in a seam it was a manufacturing defect and would not be covered. Then I spoke to a supervisor and was told that because the tear was in an outside pocket the damage was not covered and my claim was denied and "those are United's rules." How can they charge you for a service, damage your merchandise and then deny any liability?
