So it's obvious that I have a lot of spare time on my hands, but I was curious to see how they have cut the lower fares' earnings and increased the higher fares. I copy and pasted and aligned the fares in order of changes. Table C are the fares that were earned for years, prior to the arrival of COVID-19. Table B shows the changes that were made in June to try and encourage people to book Flex fares. Finally, Table A is where we are at for bookings/rebookings from today (obviously to tempt people to Comfort Flex and Business fares).
P.S; remember, if you get rebooked (for cancellation, upgrade, or flight date change), you will earn according to Table A.
