You may not want to cancel if you get a decent retention offer:

Assuming you're talking about the Southwest Performance Business Card (if another Southwest card has the 4 priority boarding reimbursements, I'm not familiar with it), that card is too new (debuted in June of last year) for perhaps anyone to have any experience yet with timing of the renewal versus the 4 priority boarding reimbursements.

New Chase WN Performance business credit card with 80k bonus

And from Chase's T&Cs regarding this card:

SOUTHWEST UPGRADED BOARDINGS

Each anniversary year you will be reimbursed for the purchase of up to 4 Upgraded Boardings which are positions A1-A15. Upgraded Boardings may be purchased at the departure gate or ticket counter on the day of travel only, when available. Price of Upgraded Boardings is based on your itinerary. Anniversary year means the year beginning with your account open date through the first statement date after your account open date anniversary, and the 12 monthly billing cycles after that each year. Eligibility for Upgraded Boardings are for accounts that switch to this product: Account open date is the date the switch is official in the Chase system. After you make your purchase with your Southwest Rapid RewardsŪ Performance Business Card, you will receive a statement credit for the price of the Upgraded Boardings. Statement credit and purchase of Upgraded Boardings may not post on the same statement; please allow up to 8 weeks for the statement credit(s) to post to your account. You may purchase all 4 Upgraded Boardings at one time or on separate flights; you will only be reimbursed via statement credit for the first four Upgraded Boardings you purchase on the overall business card account during your anniversary year. Account must be open and not in default at the time the statement credit is posted to your account.
