It appears you booked a new flight at the last minute and because of that received a C boarding position. That's certainly frustrating, but I'm not sure what anyone could have done for you at that point. The system assigns the best available boarding position so all the boarding positions ahead of you had already been assigned to someone so it would not have been possible to assign one to you. The only possibility would have been to request an early boarding position in the A1-A15 range but those too could have been sold out. Am I understanding the situation correctly? Additionally, if you want to file a complaint with Southwest you should use one of methods listed under Contact Us on southwest.com, this Community is a customer to customer forum and not setup to handle customer service issues. --TheMiddleSeat
