CLE lost 40 routes with United. Lets do some simple math. We lost BDL, but Delta picked it up. 39 to go. PHL (US Airways still there) 2 down, 38 still gone. RDU, picked up by Delta and Frontier. 37. BNA. (Southwest still there) 36. CLT, MSP, survived by US Express and Delta. 34. ATL, IND, PHX, YYZ, Delta, delta saved, American and Frontier saved, and AC still there. Got that down to 30. So this is how it looked until Frontier threw a curve ball. (a pleasant one at that) 9 weeks ago, they announce ATL, FLL, RSW, PHX (seasonal), RDU, and TPA. All were retaining service already, just new competition, with the exception of RDU which wouldve been gone. Then SEA comes along, saved by Frontier, then PHX is made year round, then DFW and LAS come in. In all, 14 destinations are made possible by F9, with 2 from Apple vacations. Big expansion. What happens next? Lets make some guesses.

Of the 30 routes being cut, a crap ton were feeder flights for a handful of mainline, all of which expect boston and phx survived. However, some important cities are left out completely of the NE OH market. Lets look:

Austin TX, growing city, growing market.
Kansas City MO
New Orleans, who doesnt love a mardi gras?

Frontier could make them work with their model, IMO.
