Even though there's a restriction on carry-on luggage there's absolutely no restriction on the amount of stuff you can carry in an item of clothing!

Here's a trick that's worth its weight in gold.
I have a Barbour Beaufort jacket I travel with everywhere no matter what the weather.
Why?
Because it has a ton of storage space in it.
You see the rules apply only to carry-on luggage but NOT on clothing. I've packed the coat with over 50lbs of stuff and just sent it through carry-on.
It's a tough coat and can be used, essentially, like a large bag.
You don't even need to be wearing it. I just carry it tucked under my arm right to the gate. It gets X-Rayed just like anything else and I go on my way.
I've flown to Europe and Canada and never had a single problem - even when it weighed more than my carry-on bag.

Try it! I've hesitated to tell folks because I fear that too many people exploiting this may provoke new regulation ... call me paranoid.

In any case, it works!
