 Southwest Airlines has entered its Swifty era. The airline announced this week that it will be adding extra flights to and from New Orleans and South Florida in October. That also happens to be when Taylor Swift's mega popular heiress tour returns to the US. The extra routes will also be something that Swift fans know all too well and include flight number 22 and flight 1989. The final show of the heiress tour is set for December 8th in Vancouver, Canada.
