💰 Check for Price or Inventory Changes
A common cause of this error is that the flight or fare you selected is no longer available at that price or has sold out between the time you selected it and when you tried to complete the purchase.
Re-select the Flight:
- Go back and re-search and re-select the flight to ensure the system is reflecting the current price and availability. The price may have increased, or the flight may now be sold out.
Verify Payment Method:
- Users have reported the error when trying to use a new credit card not saved to their profile. Try using a card that is already saved to your Southwest account, if applicable.
