Trans States Airlines, along with Compass Airlines and GoJet Airlines, is owned by Trans States Holdings and is headquartered in Bridgeton, Missouri.[1]

As of 2011, Trans States Airlines employed 650 people throughout North America. The airline currently operates over 240 daily flights in 70 cities as United Express for United Airlines. In total, TSA carried 3.6 million passengers in 2015.[2]


The company began operations as Resort Air in 1982.[3] 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.[4] 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.

Resort Air changed its name to Trans States Airlines in 1989. That same year, TSA began operations on the west coast as USAir Express at Los Angeles (LAX) and by 1995 was serving Fresno, Monterey, Ontario, CA, Palm Springs, San Diego, San Luis Obispo and Santa Barbara nonstop from LAX with British Aerospace BAe Jetstream 31 propjets.[5] By 1999, Trans States was operating BAe Jetstream 31 flights from LAX as US Airways Express nonstop to just four destinations in California: Fresno, Palm Springs, San Diego and Santa Barbara.[6]

On the east coast, in 1995 TSA began operations as a code share feeder airline into New York City JFK Airport as United Express.[3] By 1999, Trans States had begun operations as a Delta Connection code share air carrier for Delta Air Lines at New York JFK Airport with Embraer ERJ-145 regional jets and British Aerospace 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.[7]

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.

St. Louis TWA Express Hub Operations in 1990[edit]

Trans States was operating 48-passenger ATR-42 and 19-passenger Fairchild Swearingen Metroliner (Metro III model) propjets in Trans World Express code share service for Trans World Airlines at this time from the TWA hub in St. Louis with nonstop flights to the following destinations:[8]

By 1995, Trans States had expanded its Trans World Express code sharing operations at the TWA St. Louis hub and was operating ATR-42, ATR-72, British Aerospace BAe Jetstream 31 and BAe Jetstream 41, and Embraer EMB-120 Brasilia turboprops with nonstop flights to the following destinations:[9]

Current Airline Operations[edit]

Trans States currently flies solely as United Express. United Express flights are operated from both Chicago-O’Hare and Denver bases.

In October 2009, Trans States Holdings announced an agreement to purchase 50 Mitsubishi MRJ90 with options for 50 more.[13] Trans States Holdings holds 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 takes delivery.[14] It has not been announced what subsidiary these aircraft will operate for; Compass, GoJet, or Trans States.

In April 2013, Trans States Airlines began taking delivery of six former Passaredo Linhas Aéreas ERJ-145s.[15]

In 2015 Trans States began parking their United Express ERJ-145ER's, in exchange for ERJ-145XR's transferred from ExpressJet Airlines.

Previously operated turboprop aircraft[edit]

Prior to becoming an all-jet airline, Trans States operated several different turboprop aircraft types including:

These propjet aircraft were operated in code share feeder services for American Airlines, Delta Air Lines, Trans World Airlines (TWA), USAir and US Airways.[16]
