Though canceling a flight ticket has a simple step for every passenger and I wanted to book flight ticket for my Aunt. So I searched the best airline company on google and came to know about Southwest airlines. I booked a flight ticket for my Aunt and I was not knowing that her plan was changed due to some functions she wanted to attend. Now, major problem was to cancel the flight ticket and I was not knowing about a single step to cancel the flight. So, I visited airlinestips.com and caught the Southwest customer service number. How to cancel your flight on Southwest airlines? was my main concern so I asked this to the travel representative and he explained me the procedure and also canceled the flight for my Aunt. Thanks to Southwest airlines.
