OK, I take back my comment from before. I flew JAX-IAH yesterday (Friday) night at 6:38pm with a full FC (and the usual waiting list).
It was the exact same meal that I had noted as forgettable, but excused it because it was a saturday afternoon.
Nothing wrong with the meal, but it's a far cry from the usual 2 choices of 3 course meals that I'm used to on that route.
Also, I had the same unappealing BBQ sandwich and split pea soup again on Wednesday afternoon and didn't each much besides the chocolate. Sigh.
