So you're headed off to a foreign destination with your family, hauling a car seat or similar device for your infant to occupy for the hours-long flight. But once abroad, the corresponding airline says the device isn't authorized in that country and must be checked, making for a frustrating connection.

The airline industry's main trade and lobbying group wants more uniform rules on the issue.

Suzanne Acton-Gervais, manager for cabin safety at the International Air Transport Association, on Wednesday told an IATA conference on cabin safety in Paris that the body is looking for "harmonization of acceptance of foreign-approved devices on aircraft."

Officials at IATA say it is working with the International Civil Aviation Organization, a U.N. agency that has 191 member states, on the matter.
