Airport weight

As a traveler, I already made my first mistake. I was 4 pounds over on my check-in baggage. The few for four pounds is???? Take a guess. It was $200!!! Naturally, I packed really light on my carry-on so fortunately I was able to stuff some jeans and shoes and was able to get down to 49.5 pounds. We'll see how it is like when I am returning.
