Oct 25: PS menus get upgraded and look delicious
Nov 1: Domestic first flights between 1:30 and 3:59pm that are more than 3 hours get lunch

Beginning Nov. 1, the airline will refresh lunch and dinner choices for United First and United Business customers on flights throughout the U.S. and Canada, and to Mexico, Caribbean and Latin America leisure markets.

United-operated flights that currently offer meal service will addnew dishes, like Spanish paella, mushroom risotto and seafood cioppino on shorter dinner flights.

Meal window expansion

The carrier will also expand meals to:

Lunch flights longer than three hours, departing between 1:30 and 3:59 p.m., which will offer options that include seasonal entree salads like a Napa salad with grilled salmon, goat cheese and fig and an arugula salad with Milanese-style chicken; and

Late-night flights between Hawaii and Houston, Chicago, New York/Newark and Washington, which will offer full dinner service with new entrees, such as hoisin short ribs with wasabi grits and stir-fried vegetables.

Late-night non-p.s. transcontinental flights and service between Hawaii and Los Angeles, San Francisco and Denver, as well as other late-departing flights of at least five hours and 20 minutes, will offer hearty sandwiches after takeoff, such as a pretzel burger with bleu cheese dressing, arugula and pickled onions, followed by warmed pastries before arrival.

United will continue to offer its p.s. made-to-order sundaes for dessert, followed by bake-on-board cookies prior to arrival.
