Good grief! Thanks for the clarification. It makes me glad that I'm usually able to carry-on for most of my trips- trying to make heads or tails of the MSC rules is making my head spin.

But it looks like for garyschmitt, the US exception will apply to him if the US is his destination, so whatever the first operating carrier is sets the rules. Hopefully that clears things up for you, Gary.
