Utter nonsense. On AA at least (can't speak for other airlines), all meal orders are FEBO (unless it's a wide body, in which case it's ELFORB). Everybody knows it (at least anybody who reads FT) and chooses their seat accordingly, if meal choice matters to them.
p.s.. if you don't understand FEBO, it simply means that meal orders are taken Front Even Back Odd, meaning meal orders are taken starting from the front on even-numbered flights and starting from the back on odd-numbered flights. If it's a widebody with two aisles, then it's Even Left Front Odd Right Back.
Yes that is how it works on AA, but UA for one does things differently. They do a zig-zag around the cabin taking orders according to status (of course to them all UA status outranks any other *A status
). Very painful to watch and experience.
