I am chasing my 2026-2027 CP with a personal and business credit card. Chase has added a feature on their web site that shows your progress toward the SUB. For example, for the 100k SUB back in August with 5 months of time to spend $4,000, it will say something like: $3500 spent, $500 to go. Spend $500 by 01/xx/2026 to earn 100,000 bonus points. Note that pending charges are not included.
All indications on Southwest's web site are that 135k points will get you CP for 2026-2027.
