I did BEC-AAO in a Beechjet on several occasions... 3 miles between airport centers and the runways were both 18-36 with only 1/4 mile sidestep. Usually we went straight in... never even sucked the gear up

At AWAC some short ones are...

CLT-GSP
CLT-GSO
PHL-AVP
ERI-PIT (although i think that one is a thing of the past)
PHL- Allentown
PHL-MDT

We even used to do CLT-PHF-ORF... the PHF-ORF leg was blocked at 5 minutes.
