The tendency for regional flights from hubs like ORD or CLT to regional airports like FWA to get delayed or cancelled first, before mainline gets delayed or cancelled, is one reason why I no longer fly into my hometown FWA (plus the time wasted connecting, plus the cramped nature of RJs themselves and the RJ-only service at FWA). I have abandoned FWA in favour of flying nonstop DEN-IND on WN and driving up to Fort Wayne.
Food for thought: the OO FWA MX base will be seeing E-Jets soon. FWA currently lacks E-Jet service on any airline, but OO operates them for UA, AA, and DL.
If UA/OO started DEN-FWA on an E175, would it be enough for you to switch back?
And given how F9 is expanding and entering smaller markets, could we see F9 entering FWA in some form, not just returning to SBN?
