If I am an airline, I do not want you to just buy 1 ticket at the highest profit and make that profit just 1 time and do not see your face for the next 5 years, what will I gain? Only a 1 time profit. Nowadays smart customers will rather get perks and privileges and be on a frequent flyer program and be a regular customer, benefit both the customer and the company. Same goes to all other companies, this will greatly boost the global economy rather than always increasing your marketing budget to get new customers all the time. If just 50% of the global companies adopt this, the global economy will recover twice as fast. So keeping and retaining your existing customers is very crucial, and you need to know all the secrets of doing it. Very successful companies have done it, retaining as much as 50% of their existing customers this way. Contributed By Oogle.
