Hello again to sealink and everyone,

As some comments explains the " trick " of EMIRATES is to take in account the fare code of the ticket (most of time discounted one) such as Axxx fare in First (FLEX in 2015) and while downgrading to take the most expensive fare in BUSINESS : Jxxx fare (FULL FLEX in 2015).

As I wrote and show on the Blog I made this is outrageous and EMIRATES was sentenced by a French court in France :

Downgrading and refund (details) :

Court decision (English translation) :

http://emirates.over-blog.com/2017/0...n-english.html

Airlines explains (which is true) that a airline ticket with several legs is " one " thing (one contract) and, for example, if one did not check-in for first leg it is a " NO SHOW " and the whole airline ticket is cancelled.

But it appears that in order to pay a very low (unfair) refund EMIRATES tries to " changes the rules " and dares to " mix " the fares.

As a retired (old) man and as I explained and shows on the Blog I created (see above), I got (kept) screenshot of prices (FIRST and BUSINESS) of the day of my own booking to prove that Emirates had a shocking refund offer after (shocking) swaps (aircraft changes) and downgrading on two legs of my own trip.

Of course, everyone does not have screenshots of fares of its own day of booking but there is a site where you everyone can find detailed fares (before taxes) for the days of its journey at the date of the (actual) booking ! Everyone can find all fares for each day of booking for the twelve lasts months. This is very interesting to see the actual prices for example in F, A and J, I fares (and other ones). This is EXPERTFLYER where it is easy to have a free trial of 5 days and / or to subscribe for one month (this is what I made to try to understand ticketing fares) at a fee of some 10 $ :

Attached, to show how it can be useful, there is a screenshot I made (on EXPERTFLYER website) in 2016 to have a complete view of fares with : ticketing date 2015/10/02, departure 2016/01/24 and return on 2016/02/19 on CDG > CMB on EMIRATES.

I hope this informations will be helpful to everyone here.

Greetings from France.
