The myth is that the cancellation process takes very long breaks the moment you get the bookings done with Southwestern airlines. 

Keeping in mind the uncertainty of holiday planning, this aviation company has eased the cancellation process and divided the whole step into 4 points. All you need to do is visit the official website of Southwestern airlines, click on “manage booking”, write your “booking no. and the last name”, and then select the cancellation and refund option when the next page opens. 

The steps are that simple and easy. You can also call the customer service team if you have any problems.
