The two options in the Chase MileagePlus program, as of 2015, are the United MileagePlus Explorer's Card and the United MileagePlus Club Card. Both credit cards offer bonus miles redeemable with United Airlines for credit card purchases as well as extra bonus items, such as access to United Club airport lounges, free checked baggage, preferential airport service treatment and luxury hotel privileges. However, they have different annual fees and benefit details.
The United MileagePlus Explorer's Card has an annual fee of $95 after the first complimentary year. New card members receive a bonus of 30,000 airline miles if they spend at least $1,000 in card purchases in the first three months and 5,000 miles more if they add another authorized user to their credit card accounts. Card holders earn 1 mile of travel for every $1 they spend or 2 miles of travel for every dollar they spend buying tickets from United Airlines. They also receive two one-time passes per year to United Airlines airport lounges. Additionally, they receive complimentary breakfasts, room upgrades and check-in privileges at luxury hotels and resorts.
The United MileagePlus Club Card has an annual fee of $450 per year. Card holders receive membership in the United Club, which allows them unlimited access for themselves and companions to United Airlines airport lounges. Their first two checked bags are free, and they receive preferential treatment at check-in, boarding, security screening and baggage handling. Additionally, they can book United Airline tickets for close-in dates without paying an extra booking fee. United MileagePlus Club Card holders earn 1 1/2 miles of travel for every $1 they spend or 2 miles of travel for each dollar when purchasing tickets from United Airlines.
