Editorial take: Citi Custom Cash

Genuinely clever. 5% on whichever category you spent most on each month, capped at $500/month. Earns $25/month = $300/year effortlessly. Pairs with Premier to convert to transferable ThankYou Points.

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, Citi Custom Cash 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 Citi Custom Cash.
Is the Citi Custom Cash's $0 annual fee worth it compared to the United Explorer Card?
The Citi Custom Cash 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 Citi Custom Cash.
Can I have both the Citi Custom Cash and United Explorer Card?
Yes, since they're from different issuers (Citi and Chase) the application rules don't conflict. 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 Citi Custom Cash or the United Explorer Card first?
Get the one whose sign-up bonus you can hit comfortably without overspending. Citi Custom Cash: $1,500 spend in 6 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.
