THOSE of a cynical bent might think Tom Stuker a glutton for punishment. Over the years, Mr Stuker has flown more than 18m miles (29m kilometres) on United Airlines, a carrier not always renowned for treating its passengers tenderly.
Mr Stuker may possess the world’s most impressive frequent-flyer account. Over the past half-decade he has averaged over 1m miles a year with United.
Mr Stuker is extreme in his devotion. But engendering customer loyalty is something that nearly all firms strive for. Most fail. The average American household belongs to 28 loyalty schemes. The country is home to 3.8bn scheme memberships in total, according to Colloquy, a research firm, up from 2.6bn in 2012. More than half of these accounts go unused.
Frequent-flyer programmes, introduced in the 1970s, were the first examples of modern loyalty schemes. They proved to be a clever bit of marketing.
