Did you see all the money he had in the bag? Assuming that he placed what he felt was enough money to get by comfortably for a while, having a second bag stashed somewhere else with an equal amount would be an expensive option. He would either have to make a go for the 2nd bag, which would be dangerous, or throw away the cash.
I agree the airport wouldn't have been my top choice, but Gradstudent has a good take on that above. If he needed to fly out he could simply leave the gun behind.
