I've never flown into or out of Detroit before. I did my best to use the airport's website, but I just want to verify what I think I learned.
My American Airlines flight(s) from Tucson will arrive in Detroit at the North Terminal. My Delta flight for Amsterdam will take off from the McNamara Terminal. It looks like I'll have to go to Ground Transportation to take a shuttle between the two terminals.
And based on this sentence, "If you need to switch terminals, you must clear security screening before entering. Plan your time accordingly to make sure you don't miss a connecting flight." I'm interpreting this as a requirement to go through security again at McNamara. There appears to be no way to stay airside between the two terminals. Is that correct?
