I'm planning to fly from Sacramento (or SFO, if necessary) to Cancun (ultimately Playa Del Carmen) in early November. I'd like to keep it as relatively inexpensive and short-in-duration as possible. I have Alaska Air miles/certificate to use, but I'm finding they aren't real useful trying to get to Cancun......PV or Cabo, yes; but not Cancun. I'm thinking I could take Alaska Air to a city where flights to Cancun are less expensive & more frequent (maybe Dallas or Houston? Atlanta?). Need advice on this. Was thinking maybe I get to a good connecting city and then take a different airline to Cancun from there. Any input would help. Thanks!
