Yes, you can call in to order seafood meals on UA (you have to call if you want it). They are generally, if you like seafood, the best IMO Y class meals. LH's are slightly better since sometimes they give you a seafood omelet! Anyways, I stopped ordering them b/c I heard/learned that if you order a special meal, you are precluded from being op-up'd. Anyways, if you're not concerned about op-ups and you like seafood, order the meal. (This pertains to int'l flights.)
