I have a 6 am domestic flight out of DTW on American Airlines. Can I check in and go through airport the night before?
Alternatively, I am happy to go standby for a flight at 7:20 or 9:00 the night before if this is a better way to pursue this; would this work?
If I will not be allowed through security, may I hang out in the lobby until 12 am (it is a 24 hr open airport) then go through security (I will check in online 24 hr before)? Really, I am looking for a way to avoid getting a hotel.
