Pizza is coming to United economy airplane cabins and New York-style diehards are going to have a heart attack.

Next month, Chicago-based United Airlines will start selling deep dish pizza in its economy cabins, a stark contrast to the generally light and healthy fare that is typically sold onboard. The pizza will come from Uno Pizzeria & Grill, one of the biggest names in deep dish pizza in Chicago. It will be offered among other cold and warm items in the paid snack cart and, according to Travel Skills, will be a spinach and garlic deep dish served in a skillet. The airline is also planning to put together a “pizza and beer combo.”

United’s new menu items come amidst a bit of an arms race of sorts among U.S. carriers to provide the best catering across the entire air travel experience. On the premium end of that spectrum, the progress means better airport lounge food, exotic dishes in first class and even free meals in economy on some competitive transcontinental routes.

Whether the onboard pizza is more of a treat for passengers or for airline investors, one thing is certain: catering in the economy section continues to improve. According to Travel Skills, the meals will soon be sold on all flights departing from North America except for those from Canada.
