DALLAS (CBSDFW.COM/AP) — Southwest Airlines has completed a test flight from Oakland, California, to Honolulu to show federal aviation officials it should be authorized to begin scheduled flights from the U.S. mainland to Hawaii.

In a statement, the Dallas-based airline said the Tuesday flight was intended to demonstrate to the Federal Aviation Administration its long-range navigation and communications procedures and capabilities.

Southwest has applied for FAA certification to fly to Honolulu and three other Hawaiian destinations from Oakland, San Jose, San Diego and Sacramento in California.

No dates have been announced but the recent partial federal government shutdown delayed the federal regulatory approval process.
