Sunworld International Airways was a small, all-jet airline that operated in the western USA from 1983 until liquidated in 1988.

In 1984, the airline was operating nonstop service between Las Vegas and Oakland (OAK), Oklahoma City (OKC), Ontario (ONT), San Jose (SJC), Tucson (TUS) and Tulsa (TUL) with a total of 12 daily nonstop flight departures from Las Vegas operated with Douglas DC-9 jets.

[citation needed] In early 1987, Sunworld was operating its primary hub at the Reno-Tahoe International Airport (RNO) with nonstop flights between Reno and Boise (BOI), Burbank (BUR), Las Vegas (LAS), Ontario (ONT), Portland (PDX), San Diego (SAN), Seattle (SEA) and Spokane (GEG) in addition to direct service between Reno and Oklahoma City (OKC) and Tulsa (TUL) via Las Vegas.

Other cities previously served by Sunworld during its existence included: In January 1988, virtually all flights were cancelled due to financial reasons and the only scheduled route being flown was Las Vegas-Omaha.

By April 1988, Sunworld had filed for Chapter 11 bankruptcy protection and with debts of over US$15 million, operations could not be sustained.
