Chase has just upped the signup bonus on the United Explorer Business Visa Signature, from 50K miles to 75K miles: you will receive 75,000 United miles after spending $5,000 within the first 3 months of account opening.  The $95 annual fee is waived for the first year.  Our current valuation for United miles is 1.5 cents a piece, so the signup bonus is worth $1,125 in our book.  This is the best offer in history for this product! 

With certain United perks such as free bag fees, 2x miles on United | dining | gas | office supplies, as well as the annual 10,000 miles booster when you spend at least $25K per year, this is a great card to keep after the first year for United flyers and/or if collecting United miles is of your interest.

Chase has changed the signup bonus on its three personal Southwest Airlines Rapid Rewards Visa Credit Cards (Plus, Premier, Priority): from "40K + 20K" to "Companion Pass + 30K".  On any of the three cards, you will earn Companion Pass + 30,000 points after spending $4,000 within 3 months of new account opening.  Companion Pass is Southwest's potentially extremely lucrative top-tier elite status that allows you take a companion free of airline charges (not including taxes and government fees) on any Southwest operated flight as many times as you want and is normally achieved by flying 100 qualified one-way segments or earning 110,000 qualifying points in a calendar year.  This promotional Companion Pass earned by opening the credit card is good through December 31, 2019.  This bonus is not available if you currently have any personal Southwest Rapid Rewards credit card (Southwest Plus, Southwest Premier, Southwest Priority) or have received a signup bonus for any personal Southwest credit card in the past 24 months.  Based on anecdotal reports, this card is subject to Chase's 5/24 rule (you won't be approved for this card if you have opened 5 or more new accounts within the past 24 months; any new account with any issuer will count, not just with Chase; new accounts include most credit cards and charge cards but exclude non-Chase business cards and store charge cards). 

With this offer, you have a potential of saving a lot of money with the one-year Companion Pass, depending how many times you fly with a companion and where you go.  Southwest Airlines flies to most destinations in continental U.S., Mexico, some Caribbean destinations, and Hawaii (starting sometime in 2019).  Our valuation of Companion Pass is conservatively $600 based on one long trip and two short trips, which most cardmembers could realistically do.  Combined with the 30K Southwest points, the signup bonus ranges $870 to $950 in value, easily the best in history of Southwest Visa.  Previously a similar bonus of Companion Pass + 40K was offered to California residents only back in 2017.
