There are a number of people that use credit cards specific to an airlines. Most of the time, this is because there are air miles rewarded each time the card is swiped. However, when it comes to actually making use of the points earned and getting free tickets things get difficult. Seeing as credit cards are offering more competent rewards than the airlines, you may want to see which one suits your purposes better.
There are numerous cards with specific airline suffering redeemable air miles, however for those people who do not fly on a specific airline every time, it may make more sense to opt for credit cards that offer redeemable points. These points can them be retrieved against any airline rather than just one.
People complain saying their airline cards which seemed to be adding up air miles each time they book a flight according to the promotional offer just does not work when it comes to redeeming the earned air miles. There was a case where Delta Sky Miles card which offers 25,000 air miles just for signing up later would require the person to earn at least 40,000 miles before being able to use it. Plus additionally there were also fees on the card which had been waived, resulting in the customer eventually cancelling the card altogether.
The alternative option would be to go for a good credit card like the U.S. Bank's Visa card. Being unaffiliated to any airline, customers earn a point for every dollar spent. Once you earn up to 20,000 points you can cash it in for a ticket worth 400 dollars through the booking partner of the bank - Travelocity. Unlike capacity control in case of trying to redeem the card with an airline for a free ticket, you are effectively purchasing it and so there is no restriction to getting your ticket form any airline.
Senior Vice president of the U.S. Bank Bob Daly says that the main aim of the company when it decided to have its own rewards program in place was to ensure that they could deliver on the promises made to customers. This was after the merger of the visa card partner Northwest Airlines with Delta.
Following this the focus was on making sure that people can redeem once they have 20,000 points on hand and more than a billion FlexPerks points were cashed in following this change.
