My wife is looking for a return flight from the east coast to Phoenix. The cheapest she could find on southwest was around $260. Then she looked for flights to Vegas and found one for $160 that makes a stop and has a layover in Phoenix. I don't know why this flight wouldn't have shown up before but it didn't. So can she just book the cheaper ticket to Vegas and get off in Phoenix? Would there be any problems with that? When she told me I assumed she had read something wrong but I am seeing the same thing too.
