The Bombardier CRJ family and the ATR 42-600 and 72-600. Every scheduled type matched to the regional mission, with charter aircraft operated alongside it.
Sharing a common airframe and aft-mounted engines, the CRJ family cruises near Mach 0.78 and covers every hub connection from St. Louis. The CRJ-700 is the one you'll fly most.
| Aircraft | Seats | Range | Role |
|---|---|---|---|
| CRJ-550 | 50 | ~1,400 nm | Premium, low-density routes |
| CRJ-700 | 65–70 | ~1,400 nm | Core type — the workhorse |
| CRJ-900 | 76–90 | ~1,550 nm | Higher-demand hub routes |
Services: the CRJ-900 flies our four two-cabin Services — the Northeast, Mid-Atlantic, Southeast, and Western — multi-city trunk rotations from St. Louis to the major markets, in first and economy.
The ATRs are where our regional character is clearest — short, direct legs to communities the jets skip, plus cargo work. The ATR 42-600 serves our thinnest markets as a feeder; the larger ATR 72-600 covers higher-demand turboprop routes. Both are powered by Pratt & Whitney Canada PW127 engines.
| Aircraft | Seats | Range | Role |
|---|---|---|---|
| ATR 42-600 | 48 | ~716 nm | Thinnest markets — regional feeder |
| ATR 72-600 | 70–72 | ~825 nm | Short sectors, thin markets, cargo |
Entering service: the ATR 42-600 is the newest addition to our fleet, flying our thinnest-market feeder routes.
Regional Lines: the ATR 42-600 flies our four named Regional Lines — the River, Illinois, Southern, and Ozark Lines — short feeder runs that string regional towns out from St. Louis to a connecting hub, then return express to base.
Charter is a separate operating category. It sits alongside the scheduled network rather than inside it, and charter aircraft are never assigned to Lines or Services.
Note: the aircraft types above describe scheduled passenger service. Charter aircraft are operated separately and are not counted among the scheduled fleet.
| Aircraft | Seats | Role | Based |
|---|---|---|---|
| Boeing 737-800 | 162 | Whole-aircraft charter | St. Louis |
| Boeing 777-300ER | 364 | Long-range and intercontinental charter | Denver |
| Embraer Phenom 300E | 8 | Executive charter — small-party movements | St. Louis, Teterboro |
| Cessna Citation X | 4 | Executive charter — small-party movements | Teterboro |
Charter aircraft are dry-leased and flown by Confluence Air crews. They are not assigned to scheduled passenger service, Regional Lines, or Services.
CRJ-900 charter capacity: selected CRJ-900s support charter operations when released from scheduled assignments — smaller travelling parties, executive groups and regional movements where a larger aircraft would be excessive. The CRJ-900 remains part of the scheduled fleet.
