The Flights

Of course candy is fine, sealed or not. Its meat, veggies, and fruits that may be issues( but not all , and not all the time) .
Candies,cookies dryed goods in general , no one cares. Liquids are another issue .

Someone told me that it can't be over 3 oz. for liquids . True ? And thank you bunches for the help !

True, liquid and solids are limited to 3 oz. AND ALL must fit in a one quart plastic bag.

Here's the info you need about carry-on regulations, etc., from the TSA: http://www.tsa.gov/traveler-information/what-know-you-go EDITED to add: Of course, that applies only to boarding the plane in the USA. I don't have a URL at hand for the various European airport security rules, although they tend to be similar to the TSA requirements. As for bringing food into a country from abroad, i.e., getting off the plane with it, you've gotten good advice. Commercially prepared/sold items like candy are generally OK. Meats, fresh fruit and veggies, etc., can be subject to seizure at Customs usually due to concerns over agricultural pests. That's also true when you come back to the US from abroad.

Also be aware that the definition of "liquid" tends to be open to wide interpretation.

Alicia, just to be clear, the 3 oz ( 90 ml ,in metric, which is the measure of the civilized world, lol ) restriction is only for carry on liquids, you can PACK and check any size of shampoo etc that you wish in suitcase.
And in your carryon bag, any liquids must fit in a baggie. So that generally means 2-3 little bottles of stuff ( all under 3 oz or 90ml) , and make sure your make up fits in the baggie too. Its actually alot easier then is sounds, I have never had an issue with space. If taking only carry on bags just pack enough shampoo/cond for first day or so and buy some there, no biggie, they have all sorts of good stuff.

Thank you !! I wasnt sure if that 3oz. Thing would apply to the checked bags as well so thanks for clearing thay up for me !

It's also interesting to note that you may find inconsistencies to how ridged the security officers are with respect to inspecting your Ziploc bag full of liquids. A couple of years ago, I went through ORD, ZRH, MAD, and back...sort of forgot to take the baggie out for separate x-ray (like you're supposed to do), and nobody said a thing. I got used to that and started intentionally not worrying about it on all of my domestic travels. Many, many flights with nobody saying anything about not taking my baggie out of my carry-on. It was easy not worrying about it. Earlier this year...busted in Des Moines. For some reason, they were very particular. Then a few weeks ago at Schiphol, I honestly forgot to take the baggie out (but I remembered my laptop). Anyway, the officer working the x-ray asked the officer in front of me to ask me if I have liquids...oh, crap, yes...I forgot to remove the baggie...sorry. He replied that it was no big deal since they were small bottles and let it go right through. Anyway, to be technically correct, you need to have that baggie out and run it through by itself in one of those trays. That applies here (in the uncivilized world as Pat says) and in Europe.

The sign at my local airport says if you can pour it out (liquid), squeeze it out (gel), or spray it out (aerosol), it must go in your baggie - and remember, the top needs to be able to zip. The limit is actually 100ml (3.4 oz.) but most travel size bottles are 3 oz. or less. Oh, and you can only have ONE qt-size baggie.

While the rules are 3oz and everything within a quart bag, I tend to find that the security lines I've been in are lax about the bag rule, but not the 3oz rule. I have Rimowa amenity kit from a Lufthansa flight that has my liquids generally (sometimes in a zip and sometimes not). I've never had them open it up and look at it. As for packing in a checked bag, you can check any size liquids in there. Just be sure that you assume that your bag will be tossed and crushed when you pack.

TSA employees and their international equivalent are so overworked, so it's rare they can catch anything. I always keep my liquids separate in the required containers ... unless I'm so tired that I forget, and when I've forgotten they've never noticed. But I have seen them spill out things from people's containers when they see them if they exceed the limit. It's all a farce of course. Al Qaeda, if they still exist, is busy looking for other ways to strike.
