FlyerTalk Forums - Pre-ordering Meals on Delta, the Definitive Thread

The following website seems to allow you to preview the menu options ahead of time: http://cloud.o.delta.com/fltInfo

The Delta App lets you pre-select meals 7 days prior to departure. You may or may not receive an email around the same time (it's inconsistent whether you even receive an email). On the "MY TRIPS" tab, any eligible trip in the list will have a SELECT YOUR ENTREE button; this also appears if you tap on a trip and are viewing the individual trip details. The app is able to handle selections for multiple passengers traveling on the same record (i.e. you will be able to make selections on behalf of traveling companions)

PRE-COVID: If you don't get the email, or only one of multiple passengers receives the email*, you can ask a phone or Twitter/FB agent for the choices, and they can make your selection up until T-24h (not all agents are sharp about this, so you may need to explain that you want to pre-order a regular meal, *not* one of the special vegetarian/Kosher meals etc. HUCA as needed) Nowadays it is unclear if agents can even still do this (or if just the average phone/chat agent does not know how to do so anymore)

*If this happens, double check that you have an email address (for each passenger) in the reservation. (But this can happen at random anyway even if you do have an email address listed.)
