super early return to MKE National
Anyone have experience with a VERY early morning return to National in MKE? I am considering taking a 5am flight (i.e., returning about 4:15-ish?) and I believe the office is closed then. Anyone have tips/experience regarding this? Do you just mark mileage/gas on the form and put in drop box? ANyone have problems doing that?
Also, does anyone know how busy/not busy the MKE security line wait is that early? I'm assuming very light, but you never know...
Thanks!
