The word is getting around...
I was getting my haircut today and I was mentioning that to my stylist that you can go to LAS r/t from DFW for 89.00. He then told me that the guy before me mentioned the same thing and already bought his ticket.
This was not at an airport salon either.
Which raises an interesting question... one could easily steal scissors or razors from the salons scattered around the DFW gate area, I hope this has been considered.
