United Explorer Card
$150/yr · 50,000 miles + 10,000 AU bonus
Editorial take: United Explorer Card
Solid for United flyers. The free checked bag and 2 United Club passes per year add up, and the 50k + 10k AU bonus is a great starting point for domestic award flights. $0 intro annual fee, then $150.
