If you don’t already have the card in your wallet, now is also a great time to hit the apply button while you can earn up to 100,000 bonus miles — 50,000 miles after spending $5,000 in the first three months, plus another 50,000 miles after spending a total of $25,000 in the first six months.According to TPG valuations, this bonus is worth up to $1,300 in redemption value. Even if you only hit the first half of the bonus, that’s a solid $650. Spending $5,000 in the first three months may be a bit high for a consumer card, but most small businesses can hit that threshold easily. Even the $25,000 in the first six months isn’t an astronomical spending requirement for a small business that frequently spends on travel.This bonus gives you access to some great redemption options. Though United has already begun implementing dynamic pricing for post-Nov. 15 flights, you can still find sweet spots when redeeming on United metal and through Star Alliance partners.The United Explorer Business earns 2x miles on United purchases, restaurants, gas stations and office supply stores and 1 mile per dollar on everything else. It has a $95 annual fee and no foreign transaction fees.
