I just went to book a MQD run for TIJ-CUN the weekend of Sep. 8. However, when selecting seats, the connecting flight of MEX-CUN and CUN-MEX, was premier light. I selected premier at initial booking. I just want to make sure that I get the actual credit for the flight and the fare code is correct. Do I need to select another flight then to get premier on both routes or is this common?
