I was on one such flight in Feb 22, later finding out with a fellow flyer talker. He engaged with the IFL about the situation already on the plane. We both raised a complaint, not about the decision of flying stranded passengers, but about effectively the downgrade on what we paid for. BA agreed about being effectively a downgrade (status meant that we would be already enjoying lounge, fast track and priority boarding so the extra paid for CE was purely for the space) and we received a compensation offer, which I had renegotiated as I had upgraded my booking weeks after originally buying the ticket and had a receipt about exactly what I paid extra per leg (it was about £70, they originally offered £50) .this was offered in the form of a voucher, not actual cash.
