Hubby needs to travel frequently due to his job function. That's why the airline credit card is suitable for him. We know what the credit card is and know it is really hassle free when keeping one credit card inside our wallet. However, airline credit card is a bit different than normal credit card as airline credit cards allows travelers to earn airline mileage points during their traveling. Besides that, we can save money and get discounted on hotels, car rentals and other incentives. That's sound good for frequent flyers as well as my hubby! Hope my hubby can earn up the mileage points to certain amount as soon as possible, so that i can claim a free ticket to Japan.
