Not only better availability but discounts on award travel too! 10K miles off one award each year!
Adding the elite line at TSA in MKE, DCA and other airports means I never wait in line more than 5 minutes for security.
Midwest Elite status is the only way Pax are allowed to pre-book the exit row - a big deal on saver routes.
Dedicated toll-free number & agents help during irregular ops or to book award travel. Very handy.
All nice perks, although I wish bonus miles were more than 50%.
