The meals at the SFO PL at least were small portions.

And by the time you boarded and the plane took off and they started serving, it might be about 3-4 hours later.

So I haven't skipped dinner on international flights but if I could fall asleep earlier, I will try to skip next time.

My guess is I will wake up and be hungry. Maybe if and when they return to pre-pandemic mid-flight snack options ...
