We still havent booked out flights from Chicago to Las Vegas yet. We've been hoping for a deal...and no such luck yet. We are hoping to fly southwest..but at this point..it doesnt really matter. Ive signed up for airfarewatchdog.com and have been stalking southwest.com's site. The only cheap option is Spirit or Frontier and I havent heard good things about them and JetBlue doesnt fly out of Chicago. I also looked into group travel with southwest and we wont have 10 people coming back (FILs are staying a few extra days in Vegas) so we wont have enough people for the group travel. Does anyone have any suggestions? Thanks : )
