I have a flight this Wednesday that should have a breakfast (out of ATL, depart 8:55am, almost 2,000 miles, on a 737-900ER, says "breakfast" under Meal Services) that I have not been able to pre order a meal for. I called this afternoon and the agent could not even see that breakfast will be served so obviously she could not put in the order for. So I definitely did not get an email or the option to order in the 72 hour window.
