Okay, first of all calm down everyone. It's dangerous to say what is halal and what is haram unless you have solid proof, so let's not go there unless you have some proof.
As far as the Lays chips in Saudi Arabia are concerned, they are all halal as long as manufactured in the KSA - unless they are imported from outside, then you have to check.
For chips in the US - that's a danger zone. There are certain types which contain beef enzyme, and certain type which contain pork enzyme. The information is all on their main webpage. If you go to the main FritoLay page, at the top there's a link "For Special Diets". And there you'll have a huge comprehensive list pertaining to what contains gluten, what does not contain pork, etc.
A while back I sent an email to Frito Lay asking which of their products contain animal derivatives. They replied saying the only stuff which doesn't have animal enzymes are things marked Kosher (Triangle K or Orthodox Union). So we go to their site and check out Kosher products.
This is the direct link:

Only, and only those items listed there are halal in the US. Yes, sadly Flamin Hot Cheetos contain pork. Red Doritoes contain pork. Blue doritoes contain beef/chicken enzyme. Regular cheetos also contain chicken/beef enzyme. Most of their dips contain animal enzymes. The Tostitoes Salsa brand is also not halal.
Typically, the only halal lays chip flavours are plain salted, sour cream and onion, barbeque and a few others. At the store, just check if your packet has a K on it. I once found a "Salt and Vinegar" packet at the store with a "K" - even though the flavour is not listed in the site, so that means the company has started producing a few batches of other flavours keeping the Kosher requirement in mind.
If anyone wants to see a copy of the Email I received from FritoLay, I think I might still have it in my inbox, so let me know and I'll put it up for proof verification.
A silly piece of news - but the only place in the world where you can get Halal Flamin Hot Cheetos is in KSA. There are a few online hijab stores in the US which actually import and sell them online (I'm crazy, so I've once bought them online. I'm also crazy because when I went to KSA last October, regular people come back with prayer mats and prayer beads and wall hangings. And I came back with books and some packets of Halal cheetos and then me and my younger brother had a cheetos party at home. Great, now I've ruined my reputation.)
