Editorial take: Chase Freedom Flex

Worth it only if you'll actually activate the rotating 5% categories every quarter. If you won't, the Freedom Unlimited earns more on everyday spend with zero effort.

Editorial take: United Explorer Card

Solid for United flyers. The free checked bag and 2 United Club passes per year add up, and the 70k + 10k AU bonus is a great starting point for domestic award flights. $0 intro annual fee, then $150.

Common questions

Which card has the bigger sign-up bonus, Chase Freedom Flex or United Explorer Card?
The United Explorer Card has the bigger bonus, 70,000 miles + 10,000 AU bonus, worth roughly $1,040, versus $200 cash back (~$200) on the Chase Freedom Flex.
Is the Chase Freedom Flex's $0 annual fee worth it compared to the United Explorer Card?
The Chase Freedom Flex has no annual fee, so the question is whether the United Explorer Card's $150 fee is justified by its perks. If you'll use enough of the United Explorer Card's benefits to clear $150 in value annually, it's worth it; otherwise stick with the Chase Freedom Flex.
Can I have both the Chase Freedom Flex and United Explorer Card?
Yes, though both are issued by Chase so the same issuer-specific application rules apply (Chase 5/24 if applicable, Amex once-per-lifetime bonus, etc.). Many points enthusiasts hold both, they pair well when one earns flexible bank points and the other earns a different currency.
Should I get the Chase Freedom Flex or the United Explorer Card first?
Get the one whose sign-up bonus you can hit comfortably without overspending. Chase Freedom Flex: $500 spend in 3 months. United Explorer Card: $3,000 in 3 months. Pick the easier minimum spend if you're new to points; pick the larger bonus if you have planned big purchases coming up.
