I agree that the degree of air circulation within the terminal is an important factor. I’m not certain that the terminal is safer than the plane, but I think more likely than not the terminal is safer.
This link from my previous comment is not exactly a peer reviewed article, but it suggests that the difference in air replacement rate in a well-ventilated versus poorly-ventilated space (the terms they use for mixture of the air, not for air change rate) is only about a factor of 3. Of course, there are different degrees of poor ventilation.
I would be really interested to hear the perspective of somebody with greater expertise in the relevant engineering and physics.
