The cost of an extra large / non-carryon luggage case is less than the cost of a whole extra ticket With the flight regulations, especially in the USA, would you even be able to take 2 bags on? Look around for different airliners, and try to get a flight with no stopover in the USA. I've been able to carryon both a knapsack and a laptop case. Nothing said the laptop case had to contain an actual laptop either. Thing was full of a bunch of random electronics. Guy made us open it to make sure it wasn't a bomb, cause it probably looked really weird going through the x-ray.
