Didn't realize that people's experiences were so limited to AC that they don't know what other airlines offer in Y. This experience is much closer to the bottom than 'normal'.
(Hint: AC's long haul Y product no longer compares favourably to US carriers, let alone Asian ones)

To OP, I brought up the banana bread with the local AC rep quite a few months ago. Suggested they serve something a little more nutritious (forget UA breakfast offerings, even a granola bar would mark an improvement). They're aware - and evidently don't plan on addressing it.

Noted the BoB situation with some interest. There was an interesting exchange here some time ago about AC having a policy of not providing things from the BoB cart to J pax to ensure availability for Y pax. Guess that isn't going to plan.
