And mine had a correct mid-December date for my TANGO+ flight to YEG (which I intend to upgrade), so perhaps it corresponds to the pass expiry or a flight you'd booked and cancelled.
So I suppose it's more than pizza toppings that changed today, though I assume this relates to the final ending of meals on the ultra-longhauls in NAmerica, like LAX, SFO and YVR ex-YYZ. All other flights ended basic meal service a few months back (at least that was the case for YYC and YEG which still made the original cut-off).
