'round these parts, it went to court and was ruled that if the majority
of the meal was purchased at the restaurant, the patrons could not be
penalized for bringing in items which the restaurant does not serve.

Whether that would apply to other jurisdictions or not, I don't know,
but it seems reasonable.

It also seems fair that if you're paying a few hundred for a flight,
bringing a meal which the airline is unwilling or unable to provide
isn't unrealistic either.

The law isn't about fair. Beyond that, who knows.
