I just flew Allegiant for the first time SRQ to Rockford and I said I wish Allegiant would fly to Midway! That’s very exciting and maybe they will expand to more destinations?
G4 is unlikely to add MDW-FLL nonstop service anytime soon with AA, UA, WN, NK, F9, and B6 all already serving the MIA/FLL market nonstop from Chicago.
While AA, UA, WN, F9, and B6 already serve MCO nonstop from Chicago, G4 adding MDW-SFB nonstop service might be a possibility with SFB being on the opposite side of Orlando and with SFB being much closer to Daytona Beach than MCO is. G4 might also be able to capture some O&D traffic to Chicago from the north side of the Orlando metro area and the Daytona Beach area if it adds MDW-SFB nonstop service.
There are a few other nonstop routes out of MDW that could be added by G4 such as MDW-BZN, MDW-XNA, MDW-PSP, and MDW-PVU.
While G4 adding MDW-RIC nonstop service might be a possibility due to G4 already serving RIC and G4 having already announced plans to serve MDW, WN is more likely to add MDW-RIC nonstop service than G4 is with
(a) WN already having a significant FF base in the Chicago market to support MDW-RIC nonstop service,
(b) RIC being one of the top destinations that WN doesn't currently serve nonstop from MDW,
(c) WN being able to offer 1-stop connecting service to at least 14 additional domestic markets from RIC if WN adds RIC-MDW nonstop service,
(d) WN being able to make MDW-RIC nonstop service work with less O&D traffic, and
(e) the lack of MDW-RIC nonstop service being one of the biggest holes in WN's network.
