Since this is my 150th post, I thought I'd make it an entertaining g one !
So clearly an expectation of flexible is nothing more than a waiver of the change fee, and where the fare is cancelled then the $88 applies anyway. Given that situation, makes me wonder why they call it a "flexible" fare?
And I think the OP was annoyed that $110 on say his $375 one way ticket (see below) was a 30% price hike so I can understand his concern about his relative bargaining positioning....
So....
What I didn't realise is that a return domestic economy ticket is actually split and treated as two separate single one-way domestic economy fares. (Learn something new every day)

Example 7 and example 8 are most interesting because where your base fare drops you're in all likelihood stuffed, and are then you are put on the next up lowest available fare, which would result in the rather large increase in price.
Where your base fare increases then they will keep you in the same fair fare bucket and if it's more than two dollars they charge you.
So .....
How about a wonderful enhancement and actually make the Flexi fare flexible for goodness sake? No hidden traps no hidden fees no hidden opaque conditions and actually an estimate of what you might expect the fare adjustment would be should you need to apply the "flexible" aspect of your ticket which appears to be weighted heavily against the OP
The rest are food for thought but it does raise many questions that while not stated here, suggest concern (eg would you accept a price variation of 30% on electrical goods, or a house build just because?)

And it would seem the OP CONSIDERS his consumer rights have not been met here because his impression was the business ad or promotion such as to price was one thing and no way did he expect a 30% price hike would be required to invoke his rights to change his flexible ticket, which in his impression defeated the reason as to why he had paid the higher price in the first place - ie to give him the flexibility to change on demand and that his weaker bargaining position meant "he could be taken advantage of"
There's some really interesting insights on the ACDC page about creating impressions, relative bargaining strength of parties and the scenario of upfront prices where prices are changed where it's not the case of imposed fees (eg change fee) and charges. Makes for interesting discussion points.
