I'm currently a student at a university in Oklahoma and I have a few questions about internships and how they can affect interviews for jobs both positive and negative.

1. Would it be better to do an internship at a regional or major?

2. If I do an internship at a major airline, will a regional airline look down on this and believe that I'm just going to be there for a couple of years and then leave them?

3. Would an internship make an interview easier or harder? Would I be expected to know more than others my age that did not do an internship?

Any feedback from anybody on these forums will be greatly appreciated.
Thanks for your time.
