Am flying to France, with carry-on luggage only.... all liquids -3 oz. in ziploc bag of course. We're also flying WITHIN France. I've heard they don't allow ANY liquids/gels carry-on on flights within Europe. Anybody know?

You heard wrong.

The same rules apply as on transcontinental flights as far as I know. Certainly inter-European flights have the same rules, so i see no reason why a flight with France would be different. Each Airline is free to impose it's own carry-on rules, with regard to size and weight, but the liquids rule is a security rule, internationally agreed.

It was OK last week.

Do check carryon size restrictions though - some airlines allow what you have on your transatlantic, some don't, and are more restrictive. It could be by weight or size.

You might also post this question on the Europe board for additional answers.
