I'm very disappointed that we're back to getting useless aircraft change alerts when there has been no change to aircraft type. I understand how it works with European carriers constantly flexing their J/C and Y cabins and that others see value in it that I don't, and I'd still like this to be an option so they can get what they want while I don't get constantly bothered by totally pointless alerts, but the last couple of days I'm also getting no-change change alerts for flights on WS 789s, for which there's definitely only one layout and nothing at all to flex.
