It’s not hard to get around the airport but it can be a long walk

you have a train connecting C, A, and main terminal and a train connecting B and main terminal thrn there is the mobile box from D to main terminal and I think to A as well

also what kind of plane coming in in? If you are flying a large plane it take longer to get out than a crop duster

if you fly United in you could be on a smaller regional and come into A 1-6 tarmac gates

do you want to get food before your int flight? That adds time
