Reservations agent for Southwest Airlines, leaping over policies with a single bound. faster than a speeding...
what you are able to do is call our reservations center and speak to an agent. Let them know that what you told us here on INSDR. They can check to see if there is still room available on the flight you want and possibly give you the price you saw.
Let me tell you what may have happened. When a person gets knocked off the sight for any reason is usually 1 of 3 things. 1, your internet provider is having issues, 2 if you started to make a reservation and walked away and didnt finish it then came back to it, the system timed you out or 3. When you were making the reservation someone else was making the same reservation and got the last seat at that particular price and the system was updating the site to reflect the new prices.
Again call our reservations center and speak with and agent and see if they can help you. If they say they cant ask to speak to a supervisor and they are able to give you the price you saw unless the flight is sold out already, at that point there is nothing they can do but try to find an earlier or later flight for the price you saw.
The number for the reservations center is 1-800-IFLYSWA (1-800-435-9792)
I hope this information helps you.
