United’s roomier Premium Plus seats on sale
United's roomy new international premium economy cabin, which it calls United Premium Plus, will be officially introduced on its 777-200ERs, 777-300ERs and 787-10s starting March 30, and should be available on 21 global routes from three U.S. hubs – San Francisco, Newark and Washington Dulles -- by the end of May.
United has been refitting its existing aircraft for several months with the new purple premium seats being offered as Economy Plus extra-legroom seats (at no extra cost) until a full roll-out was ready. United now says its new Premium Plus seating category will go on sale December 3.
