Southwest Airline Ads

This new Southwest Airline ad has go to go. It keeps freezing up the screen while it loads, and it loads whenever I open a new web page or when I sit too long on a web page (about every 30 seconds). It has interrupted me 6 times as I write this, because I keep having to waste time waiting for it to load or rewrite something it screwed up.
