I've noticed that a lot of people don't really seem to have a problem with the carry-on bag checks.

I want to address the rescan on xray of some bags. The reason for a rescan sometimes, is to get a different angle on the bag, lay the bag down, or because of a weird image. The rescan can usually save a bag check.

But if a bag check gets called at one airport but not another, don't get to upset. Remember each airport has a different set of screeners, who are more comfortable on the xray then others. Maybe the screener at the first airport just wasn't sure what the item was, so had it checked. But the screener at the next knew exaclty what it was and didn't have to check.

Honestly, on a daily basis, we see at least one or two new items on the xray.

My airports policy is we can tell you what we're looking for and even ask you to point it out if you can. But we can't give you access to the bag until we've cleared it after a bag check has been called.
