Air France Frequence Plus - Same fares but differente prices...?

A week ago I bought a flight XXX-CDG-Intercontinental-CDG-XXX on Air France in Premium Economy (fares W-A-A-W).

Today, I've search the same flight, in same fares (W-A-A-W), and the price IS LOWER...!! :confused::confused:

I don't understand it... :td::td:

The fare is more than just a letter. It is generally a 6 (or more, I do not recall) letter code.
Moreover, is it a 2€ difference or 20€ or 200€.
The taxes levied by airport are in local currency, so if the EUR becomes stronger, you can earn a couple of EUR.
They also might have reevaluated the price of your ticket after market analysis.

Hello GuillaumeD,

The difference is 100 EUR. The taxes are exactly the same.

I won't ever get to know how the fare-price systems in airtravel work... :(:(

Thank you for your information ;)

Are you surprised that prices go up or down over time depending on supply and demand?

It is common that cheaper fares become available over time if the load on a flight is light. On the other hand, fares could increase over time if the load becomes higher than expected. And if you book six months before a flight, there is a chance of a promotion campaign that will reduce the fare offered. So booking early is always a gamble. You are sure to get on a specific flight at a known cost, but you might miss the opportunity for a cheaper fare offered later on that same flight.
As GuillaumeD mentioned, the first letter of a fare bucket (e.g. A or W) is not a sufficient descriptor of the fare as several A*** or W*** can exist at the smae time with different conditions and price.

Thank you very much, Brunos. I really didn't know how it worked; I assumed that the letter distinguished a fare from the other and, so, same letter=same price.
I thought that the ups and downs in prices over time were due to the fact that the airline put on the market new "letters".

It's good to learn something new! :)
