I was not knowing about how do I add an infant to a Southwest flight? And I wanted to travel to Canada with my child to spend vacations. So to resolve my main concern I get help from airtickethelp by visiting their website and got southwest airlines contact number. After that, I contacted them and ask everything related to flying with my child. I was little worried, but they solved my query calmly and explained me with detailed information. Thanks to Southwest airlines customer service team.
