I'm sure no one has come across this yet, but Southwest now prevents you from changing an itinerary if there is a companion associated with. I can understand that... however it doesn't even let you see what the current fares are --- it stops you right when you hit change.

If it's not already obvious why this is so annoying, I now need to book a separate flight with the same dates and times to see if the fare has dropped -- or, don't add the companion until I "believe" I've found the best price.

I really hope they change this.
