Reply To: Downgrade compensation advice

[maybags]

It looks like BA like to dig their heels in with downgrade refunds, which is extremely frustrating. Not only does it cause stress at the airport but then a further fight for the proper level of reimbursements.
Can I ask how to calculate 75% of the fare difference? What base rates should I be working from as I obviously cannot see what a wt+ vs wt fare is now our flight has passed? Thank you.
