In the past, when flights to different places were still getting better connected, the companies that ran the flights were rude to their customers. But the things have changed completely since then. Now that there are so many airlines competing for customer attention, the customer has become king. The frequent flier credit cards are a treat for the king. The more you fly, the more rewards you get. The idea came from the need for frequent fliers to build a loyal customer base. There is a big difference between travelling by train and travelling by rail.
Once an aeroplane has taken off, the empty seat can't be filled, but that's not the case with a train. So, to fill as many seats as possible, incentives had to be given. These incentives came in the form of credit cards for frequent flyers. Frequent flier credit cards are a type of co-branded card. They are issued by the airline, the bank that is issuing the card, and one of the card companies, like Visa or Master. The goal is to build a group of loyal flyers, especially business travellers who take more than five or six trips a month.
Every time a frequent flier credit card is used, it turns into benefits that the cardholder can see and feel. The first benefit of having a frequent flier credit card is that you can use your frequent flier number to check in over the phone. For a business traveller, being able to confirm his boarding on the flight is a big help, since you might be kept waiting until the last minute and it might be hard to check in when you get to the airport. On the other hand, you may be able to keep your meeting going until the last minute because you have already told the airlines that you will be there.
Once tele-check-in has been done, the person with the frequent flyer credit card can also confirm his seat. All you have to do is land at the airport, get your boarding pass, and you're off to your destination. Access to concierge lounges is another perk of the frequent flyer credit card, especially when you are travelling outside the country. The fact that you don't have to pay to use concierge lounges is a big plus because you can easily kill time there between flights. The person who has the frequent flier credit card also gets bonus points every time they tele-check in. The first perk for people with frequent flyer credit cards is that they can move from economy class to business class or even first class without having to pay the difference.
It is kind of like a reward for taking a certain flight. The second benefit of having a frequent flier credit card is that you can get free travel vouchers. This free travel voucher is a gift that you can also use to win over your wife, who might be annoyed by how often you go away. It seems that the companies that give out frequent flyer credit cards know this, which is why the free cards they give out also give the wife the chance to choose that airline.
