RSV at any airline sucks.

RSV at SWA is 96TFP/mo.

You will be on RSV for 2/yrs at every base except OAK/LAS.

4-5 years in MCO (most sr base at the moment).

SWA does give you the ability to trade days off for trips. Seniority gets you better trips on those days, but you can easily get 110TFP with 13 days off.
