# Trans States Airlines

Trans States Airlines was a regional airline in the United States that operated from 1982 until 2020, when it shut down due to the COVID-19 pandemic. It was owned by Trans States Holdings and headquartered in Bridgeton, Missouri. At the time of its closing, the airline operated flights for United Airlines under the United Express brand. Trans States Airlines ceased all operations on April 1, 2020.

## History

The company began operations as Resort Air in 1982. As an independent commuter air carrier, Resort Air operated Swearingen Metro propjets from a small hub located in St. Louis (STL) with service to Carbondale, Illinois; Columbia, Missouri; Fort Leonard Wood, MO; Joplin, MO; Lake of the Ozarks, MO; Springfield, IL; and Springfield, MO. In 1985, the company entered into an agreement with Trans World Airlines (TWA) to operate as Trans World Express serving six cities in Missouri and Illinois. In 1989 Resort Air changed its name to Trans States Airlines. Many new aircraft were added to replace the Swearingen Metro planes including the BAe Jetstream model 31 and model 41 as well as much larger ATR 42s and ATR 72s. New service was added to many more cities from St. Louis and in 1999, Embraer ERJ 145 regional jets were added for the Trans World Express system expanding service to several cities much further distant from St. Louis.
In 1993 TSA began operations on the west coast as USAir Express at Los Angeles (LAX) with service to Fresno, Monterey, Ontario, CA, Orange County, Palm Springs, San Diego, and Santa Barbara nonstop from LAX with BAe Jetstream 31 propjets. The operation continued until the year 2000.
On the east coast, in 1995, TSA began operations as a code share feeder airline into New York City JFK Airport for both Trans World Express and United Express. By 1999, Trans States had begun operations as a Delta Connection code share air carrier for Delta Air Lines at New York's JFK Airport with Embraer ERJ 145 regional jets and BAe Jetstream 41 propjets with nonstop service to Albany, NY, Baltimore, Greensboro, NC, Hartford/Springfield, Norfolk, VA, Philadelphia, Pittsburgh, Raleigh/Durham, Richmond, VA and Rochester, NY. Flights under the USAirways Express banner were also performed at Pittsburgh.
In December 2001, TWA merged into American Airlines and all Trans States flights operating as Trans World Express then began flying and American Connection. American later dismantled the St. Louis hub operation created by TWA and the American Connection flights ended in 2009. In 2015 American merged with US Airways and the US Airways Express flights operated by Trans States then began flying as American Eagle. These flights then ended in 2018.
In 2006 Trans States briefly operated a small hub at San Antonio, Texas flying Embraer ERJ 145s. The service was performed under the United Express banner with flights from San Antonio to Albuquerque, Colorado Springs, Kansas City, New Orleans, Oklahoma City, Omaha, and Tulsa.
The call sign "Waterski" and the ICAO 3-letter identifier "LOF," which stands for 'Lodge of the Four Seasons', are from the early days when the company was operated as Resort Air and took visitors to the Lake of the Ozarks in Missouri.
In 2015, the airline began a hub operation at Denver under the United Express banner and carried 3.6 million passengers for the year.
In February 2020, Trans States announced their intent to gradually cease operations through 2020 and transfer their fleet of ERJ-145's to ExpressJet Airlines per an agreement with United Airlines. However, on March 17, 2020, CEO Rick Leach sent a memo to employees stating that due to the impact of the COVID-19 pandemic on aviation, the airline would cease operations on April 1, 2020, much earlier than originally expected. Compass Airlines, another regional airline owned by Trans States Holdings, also announced a cessation of operations effective April 7, 2020, leaving GoJet Airlines as the only operating airline owned by Trans States Holdings. The ERJ 145s that were transferred to ExpressJet were then transferred to CommutAir later in 2020 as ExpressJet was subsequently shut down. CommutAir is also a United Express operator.
The final Trans States Airlines flight was United Express Flight 4695 from Springfield, Missouri to Denver, Colorado on April 1, 2020.

## Fleet

Prior to its shutdown, the Trans States Airlines fleet consisted of the following aircraft:
Trans State Airlines Fleet :
| Aircraft | In service | Passengers | Operated For | Notes |
| Embraer ERJ 145 | 45 | 50 | United Express | Most transferred to ExpressJet and then CommutAir. |
| Total | 45 | | | |

### Fleet development

In October 2009, Trans States Holdings announced an agreement to purchase 50 Mitsubishi MRJ90 with options for 50 more. Trans States Holdings held conversion rights to take the smaller, 76-seat MRJ70 instead of the 92-seat MRJ90 dependent on the scope clause environment by the time the airline took delivery. The order was cancelled as of October 2019 due to concerns that the Mitsubishi SpaceJet M90 aircraft violates the US Scope clause laws.
In April 2013, Trans States Airlines began taking delivery of six former Passaredo Linhas Aéreas ERJ-145s. In 2015 Trans States began parking their United Express ERJ 145ERs, in exchange for ERJ 145XRs transferred from ExpressJet.

### Previously operated aircraft

Prior to becoming an all-jet airline, Trans States operated several different turboprop aircraft types including:
* ATR 42
* ATR 72
* BAe Jetstream 31
* BAe Jetstream 41
* Embraer EMB 120
* Fairchild Metroliner III
These propjet aircraft were operated in code share feeder services for American Airlines, Delta Air Lines, Trans World Airlines (TWA), USAir and US Airways.
