Well...I was gardening away but will be traveling more on business. The Points Guy rates Jet Blue Mint as the best domestic First Class. So...I considered applying for the Jet Blue Plus card. The 30,000 mile bonus after only $1,000 spend pushed me over the top! 
Instant approval for $4,000 (TU 678). This is my second Barclaycard product; I've had the Arrival+ MC but with half the SL. I use it occasionally but not heavily, so no CLI yet.
