The Mid South hub also operates a high frequency service to Eldorado, Harrison, Hot Springs and Jonesborough from Memphis.

It has a unique selling point in that it uses small terminal facilities which do not require passengers to undergo the full US security process. This allows 15 minute check-in times and quick disembarcation.
