I refer to the comment of user Relaxed under this answer:

It's also useful to enforce the “non-changeable” fares which is another price discrimination strategy.

Please explain? What's the user Relaxed assuming? Does he/she assume that airlines forbid transferring of tickets to another person? Does this assumption matter?

  • What's the travel question? Sounds like economics or business strategy, no? – Mark Mayo Oct 14 '14 at 7:07
  • If you have a non-refundable fare but you can get your money back by selling it, then it's not really non-refundable. – Relaxed Oct 24 '14 at 7:06

I think what Relaxed meant by "non-changeable fares" is tickets that are only valid for one specific flight at a given time and date and cannot be rebooked (or only for a considerable fee).

Price-sensitive passengers will book those fares, but other passengers (mostly business) are willing to pay much higher fares for the luxury of not having to worry about catching a specific flight and instead being able to just walk up to the checkin counter and take the next one.
