Confident that your carry-on bag is OK to take on the plane?

We were until we spotted this sign in the boarding areas at Seattle-Tacoma International Airport (SEA).

It lists the carry-on bag restrictions issued by each airline. And very few of them are the same.

The chart evidently strikes fear – of confusion – in the hearts of many other travelers as well.

We posted a snap of this chart on social media just before boarding an early morning flight and by the time we landed, four hours later, there were more than 16,000 views.

Yes, there are different airplanes and different-sized overhead bins. But wouldn’t it make shopping for a carry-on bag a bit easier if the airline size restrictions and maximum measurements for those bags were a bit simpler and more uniform?
