totally depends who is flying and what is happening in destination. For the last two years, I've been booking flights in lots of 30 for three month periods, same flights on same day of the week range a great deal for no apparent reason. I can book a flight a few weeks in advance for rock bottom, and one for eight weeks near the top end... ie EUR 30 v 95.

If your dates are set in stone, book the flights, prices never go down on easyjet.

That is true, but in this case, within the time that you book, then change the date of the ticket (24 hours minimum later), the chances are small I would say for the desired flight date to be sold out (as you would make sure that the flights on the desired day would not be sold out when booking), especially as the flights is 3 months out.
But there is a risk that it does sell out yes, and the prices rarely go down on Easyjet (I have seen it only with promotions, like the recent one out of Lisboa for the anniversary of Easyjet having a hub there I think)

That's not true.

Set up an email price alert with skyscanner for a route that easyjet fly, and it's possible to see that their prices can go down as well as up.

(It's worth bearing in mind the easyjet price promise - they don't promote it these days but it still exists. Should you buy a flight and it subsequently goes down in price, then you can reclaim the difference as a credit voucher - this can only be done by telephone, and the credit voucher is only valid for 6 months, but nonetheless it could come in handy. All detailed in Article 26 of easyJet's terms & conditions.)

Regarding Daemon's question about whether there could be no availability on a desired flight - always possible I suppose, but highly unlikely three months out (worth checking the desired flight first though). I'd go for it.

Perhaps the primary purpose of the new 9.2.2.1 clause is to prevent people booking a cheaper flexi fare for imminent travel, i.e. within the next 24 hours. I guess it also functions as a way of creating a little uncertainty for those in position such as Daemon.

So I'm about to take advantage of this Flexifare "loophole" by buying a Flexi ticket for the 17th at £80 and then moving it back a week to the 24th (which would cost me £123 right now). But just to complicate things a little, I'm paying an extra £13 for an additional piece of checked luggage... if I booked the 24th, this would cost £14. So when I book the 17th at £93, will I then be charged an additional £14 for the second bag after I move my flight to the 24th (making it £107 in total), or will the second bag be transferred seeing as it was already paid for?

Cheers in advance...

Guys - trying to learn this so wanted to validate here

ORY-PSA (paris to Pisa) Sept 8 14:35 Flexi fare showing 126 euros
On Sept 4, it's showing as 83 euros

Can I simply book the second one, then few mins later go back and make the change to fly on sept 8 and not pay anything more? Not even the fare difference?

Thx

No. Check this thread and 9.2.2.1 of the terms and condition. 24hrs wait applies.

guys - i waited 24 hours and tried to change the flight to the 8th for 14:35 but it didn't give me the option. It only gave me the 7am or the 18:30 and i chose the latter
I guess flexi fare does allow you to change flights but they don't give you all options even if seats are available and they are on the 14:35

Any workaround?

if ya gonna cheat the system, perhaps don't shout about it.

ok but that doesn't answer my question

There is no such flight. Which would be why you can't change your ticket for it.

Easyjet flexifare
 

Having read the previous comments regarding changing dates with flexifare and not having to pay any increase in flight cost. Has the following been added to the Easyjet T and C's. If so, it now states that you WILL have to pay any uplift in price.

Article 9 Flight Transfers & Flexible Fares (“easyJet Flexi”)

9.1 Flight Transfers

9.1.1 Passengers can transfer Flights (that is, the date and time or the route of the Flight) for an administration fee per passenger per Flight (see Our Fees and Charges), plus any difference between the original fare paid and the lowest fare available for the same Flight at the time the change is made. If the available fare is lower than the original fare paid, no refund will be made.

Any thoughts?

Again, I understand that section 9.1 is for regular flights and 9.2 is what applies to flexi fares.
