If you’re looking for a number to call when you have a problem with Southwest Airlines, you can try 832-645-0001. This is the number that Southwest uses for customer service. But be warned, this is not the best number to call if you need to speak to someone in a hurry. For example, if you want to cancel your flight or get a refund, calling this number is not going to work very well. Instead, try one of the other numbers listed on their website, like 832-645-0001 or 832-645-0001. These numbers are specifically designed for customers who need help right away.
