If you will be flying more I would suggest looking into a status challenge for Gold or Platinum status instead, you will get earlier boarding, checked baggage, bonus mileage for flights, free same day standby, waived close in award charges and access to MCE seating for free and you would be eligible for upgrades (which are admittedly rare as a gold or platinum).
