In my business class we learned about a statistic called "80/20" which states that 80 percent of sales comes from 20 percent of the customer base. This was with regards to B2C (business to consumer) retail sales.
Can or does this statistic apply to airlines, that 80% of flight tickets are bought by 20% of total paying passengers, i.e. the business traveller or frequent flyer? Are they who the airlines target new promotions to?
What about the other 80%, vacationers and seasonal folks and sweepstakes winners?
