The JetBlue Card from American Express is designed for those who travel frequently with JetBlue Airlines and would like to take advantage of the airline reward program. Through the reward program, cardholders earn one Award Dollar for each dollar spent on the card. Two Award Dollars are earned for each dollar spent on JetBlue flights, restaurants, movie theaters, gym memberships, event tickets, and golf green fees. It is important to understand that 200 Award Dollars are equal to one TrueBlue® point, and 100 TrueBlue® points are equal to one round-trip flight. Cardholders receive 5,000 bonus Award Dollars after the first purchase, which equals 50 TrueBlue® points toward a free round trip ticket. There is no limit to the amount of Award Dollars that can be earned, but TrueBlue® points expire one year after they are earned, and TrueBlue® awards expire one year after they are issued. In addition to the reward program, cardholders can expect common benefits offered by American Express, such as various emergency assistance services, purchase protection, extended warranty services, and up to $100,000 in travel accident insurance. The annual fee of $40 is reasonable as compared to other airline reward cards. There is a 3.99% introductory rate for six months that applies to balance transfers submitted with the application, and the interest rate is above average for purchases and balance transfers once the introductory rate expires. Therefore, those who can afford to pay in full each month after the introductory rate expires (to avoid finance charges) and plan to take advantage of the reward program will benefit most from what the JetBlue Card from American Express has to offer.

The Platinum Delta SkyMiles® Credit Card from American Express, is by far the best of all Delta SkyMiles® Cards and is designed for those who have a very good credit history. Cardholders receive one mile for every dollar spent on general purchases and two miles for every dollar spent at participating retailers and merchants (including Delta Air Lines related purchases). Twenty thousand bonus miles are awarded to new applicants with their first purchase, 5,000 of which are Base Miles to be applied towards the Medallion Status program for upgrade opportunities, mileage bonuses, and more. Miles do not have an expiration date (if travel is made through Delta Air Lines at least once every two years) and there is no yearly limit, unlike the gold and standard cards that do have yearly limits (based on annual spending). Although the annual fee of $150 is not an attractive feature, it is reduced to $95 for those who already have an American Express® Charge Card. The card offers a very low introductory rate of 3.90% on balance transfers for the first twelve months, provided the balances are transferred during the application process. The APR for purchases and balance transfers is above average for a reward card. Cardholders can expect many of the common benefits and services provided by American Express®, such as auto rental insurance, travel accident insurance, year-end financial statements, and various purchase protection related services. Therefore, those who plan to spend at least $3,000 or more a month due the card's high annual fee, frequently fly on Delta Air Lines, and will use the card at participating retailers and merchants (to accumulate additional miles) will benefit most from what the Platinum Delta SkyMiles® Credit Card from American Express has to offer.

The Gold Delta SkyMiles® Credit Card, issued by American Express, is designed for those who frequently travel using Delta Airlines. Cardholders receive one mile for every dollar spent on general purchases and two miles for every dollar spent at participating retailers and merchants (including Delta Airlines related purchases). Additionally, 20,000 bonus miles are awarded to new applicants with their first purchase, and 5,000 bonus miles are awarded for two approved additional cards submitted with this application. Miles do not have an expiration date (if travel is made through Delta Airlines at least once every three years); however, after the cardholder reaches $100,000 in annual spending, only one mile will be awarded per dollar spent. Cardholders will also have access to the exclusive Pay with Miles benefit. Through Pay with Miles, cardholders can pay for a portion or all of their airfare with miles and put any remainder of miles back on the Gold Delta SkyMiles® Credit Card. Start redeeming Pay with Miles at 10,000 miles. The annual fee will be waived for the first year. After that time the annual fee is $95; however, for those who already have an American Express® Charge Card the fee is reduced to $40. The standard APR for purchases is above average for an airline reward card and not ideal for those who plan to carry a revolving balance. There is an introductory rate of 9.99% offered for balances transferred during the time of application, which applies for the life of the loan. In addition to the reward program, the card offers many of the common benefits and services provided by American Express®, such as auto rental insurance, travel accident insurance, year-end financial statements, and various purchase protection related services. Those who can afford to pay in full each month (to avoid finance charges), will use the card at participating retailers and merchants (to earn additional miles), and will be able to accumulate enough miles to redeem a free ticket or other travel related services within a two-year period (especially if paying the $95 annual fee) will benefit most from what the Gold Delta SkyMiles® Credit Card from American Express has to offer. Those who are looking for additional frequent flyer benefits may want to consider the platinum card, which comes with a higher annual fee of $135 and has a higher credit qualification requirement.

The Delta Reserve Credit Card, issued by American Express®, is fit for Delta frequent flyers with good credit who want to earn miles with little effort. Although the rewards program offers the standard one mile for every dollar spent on purchases, cardholders will be happy to know that they can earn Always Double Miles® for every eligible dollar spent buying groceries, at drugstores, home improvement and hardware stores, gas stations, and for certain U.S. postal services. Cardholders can pay for all or part of their flight with miles earned through the Pay with Miles option. For cardholders who are interested in earning miles more speedily, they will rack up to 10,000 Medallion® Qualification Miles (MQMs) after making their first purchase with the card. Cardholders will also earn up to 30,000 MQMs with Built-in Miles Boost(SM) for spending $30,000 in one year. If they spend $60,000 in a year, that will add an additional 15,000 MQMs and bonus miles toward their reward account. MQMs can either be used towards upgrading to Medallion® status or passed on to friends and family members who have Delta SkyMiles® accounts of their own. Every year, cardholders will also be awarded a free companion certificate for domestic travel in either coach or first-class. In addition to the bonus miles that can be earned, cardholders will have access to a wealth of American Express® benefits. Some of the conveniences offered include concierge services, car rental insurance, travel accident insurance, roadside assistance, and emergency services if a card is ever lost, Global Assist® access, and a year-end summary of all account activity. There are also a few protection services available to cardholders which includes extended warranties, purchase return and protection, and a fraud protection guarantee. For an airline miles card, the interest rates for this card are somewhat above average for purchases and balance transfers. There is no introductory rate offered, but there is a reduced annual fee of $395 for eligible existing American Express cardmembers, otherwise the basic annual fee is $450. Additional cards are available, but will be $175 for a Delta Reserve Credit Card. Bottom line, the Delta Reserve Credit Card is perfect for people who can spend enough to maximize the benefits of carrying the card. An ideal card carrier should not have a problem with the above average rates and may even take advantage of the balance transfer offer which is good through the first 12 months of opening an account.

The WorldPerks® Visa® Platinum Card, issued by U.S. Bank, is ideal for those with very good credit who travel regularly on Northwest Airlines® or any of their airline partners. Through the rewards program, cardholders earn one mile for each dollar spent on purchases. Up to five miles per dollar can also be earned at participating restaurants. Upon approval, up to 10,000 bonus miles are applied to the account. Earned miles can be redeemed for free travel with Northwest Airlines® or any of their partners. Although miles do not expire, there are some mileage restrictions. For instance, those who spend more than $60,000 in any calendar year or over $10,000 per billing cycle will be limited to one mile for every two dollars spent over that amount. Nevertheless, those who prefer to have their credit card bill automatically paid in full each month (or are members of Northwest® WorldPerks® Platinum Elite, Gold Elite, or Silver Elite) will be exempt from all reward limitations. For an airline reward card, the $55 annual fee is considered reasonable, but the interest rate applied to purchases is above average. It is important to note that the APRs for all transactions are tied to the highest Prime Rate during a three-month period. Due to this policy, the APRs may never reach the lowest possible interest rate. In addition to the rewards program, cardholders can expect common platinum benefits offered by U.S. Bank that include up to $1,000,000 in travel accident insurance, auto rental insurance, purchase protection services, and online account access. Therefore, those who can afford to pay in full each month (to avoid finance charges), plan to sign up for the auto-payment option (to avoid reward limitations), and will be able to earn a free ticket or other travel related service within a two-year period (due to the annual fee) will benefit most from what the WorldPerks® Visa® Platinum Card has to offer.

The WorldPerks® Visa®, issued by U.S. Bank, is ideal for those with excellent credit who travel regularly with Northwest Airlines® or any of their airline partners.

Although the $90 annual fee is slightly high and the interest rate for purchases is above average for a reward card, the signature card has no pre-set spending limit. It is important to understand that the APRs for all transactions are tied to the highest Prime Rate during a three-month period. Due to this policy, the APRs may never reach the lowest possible interest rates. Cardholders should also be aware that the signature version of this card does not allow balance transfers. In addition to the rewards program, cardholders can expect common signature card benefits offered by U.S. Bank, such as a personal concierge service, travel accident insurance, auto rental insurance, purchase protection services, and online account access. Nevertheless, this card has fewer benefits compared to other signature cards. Therefore, those who can afford to pay in full each month (to avoid finance charges), plan to sign up for the auto-payment option (to avoid reward limitations), and will be able to earn a free ticket or other travel-related service within a two-year period (due to the high annual fee) will benefit most from what the WorldPerks® Visa® has to offer.
