757 being used for the wrong flight?

So when I was younger and I flew from KRIC to KATL, we would use the MD-80. Now Delta uses a 757. When I first saw this happening I was shocked! They are using a 757 for a 1.5 hour flight! I think Delta could be wiser and use a plane like the A320 or Crj-700. What do you guys think?


Not substantial enough to need a discussion
