Southwest Airlines flies from Midway Airport in Chicago, Illinois.
Southwest Airlines makes its maiden voyage to Hawaii this week – but there won't be any vacationers on board.
"It has affected our certification process for Hawaii," said CEO Gary Kelly. CNBC last month about the closure.
The airline's decision to offer service to the Aloha State has rattled the stock to competitor Hawaiian Airlines. In what is called "Southwest Effect", the prices of $ 45 are lower in markets where the airline has nonstop service than in cities without these routes, a study from the University of Virginia found.
Southwest plans to offer Hawaii flights from the west coast as well as intra-island service.
