Instead of using the same flight number on a round trip, i. e. DFW - LAS - DFW, I would have preferred that they add more direct flights using one flight number to cover two city pairs. I. e. FLL - DFW - LAS. That way the same flight numbers would not be reused between two cities as they have started doing. I think using the same flight number on an outbound and return journey is prone to cause customer service issues.
