Haven't seen $240 RT in a long time. Sure, there are deals on Spirit and decent rates if you connect, but Delta and Sun Country.... it has been a while. Delta didn't give me all its flight options, but it gave me decent ones for $260. Sun Country, however, offered me RTs for $240. It has far fewer flight options, but the only drawback to the option I chose is that we'll say in Vegas a few hours longer than I'd prefer, but that's hardly a sin! And Sun Country is not as hectic as Delta since you get to use the smaller, less ridiculous terminals.
