Which flights/airlines have the most flexible terms?

[CRUELLA]

I have a couple of bookings ok maybe 3 😂 under the zen guarantee.I’m thinking of looking for flights for one of the dates .nervous to commit as these dates are in winter .what could happen is anyone’s guess between now and then !
What airlines have the most flexible terms at the moment? We can fly from Leeds,Doncaster or Manchester

I'm flying from Newcastle with Air France in November. I can do the following:

Changes
You can change the date and/or destination of your ticket, regardless of your ticket’s fare conditions, up to the day of departure of your first flight. If the price of your new ticket is higher, you will only pay the fare difference.

Refunds
You can request a ticket refund at any time before the departure of your first flight, for any trip scheduled on or before 31 December 2021. If you purchased a non-refundable ticket, you will receive a voucher valid for 1 year. This voucher can be refunded at any time during its validity.

I also did a dummy change to check how much it would be to move it 2 weeks earlier and it was a total of £8 and looked very easy to do.

My biggest concern is that my DD turns 18 10 days before we go on this trip but Disneyland won't let me keep the incentives if I move it.

I'm not sure which other airports Air France fly from.
