New York Air was an early entrant into the American airline industry after Deregulation went into effect. The Texas Air Corporation—headed by notorious airline baron Frank Lorenzo—set up New York Air in 1980 at LaGuardia Airport. From there, they initially would compete with Eastern on the lucrative “Shuttle” routes out of LaGuardia to Boston-Logan and Washington-National, with flights leaving every hour.
Reno Air was, for the most part, a successful operation; finding it’s place as a solid regional carrier in the Western US. Alas, Reno Air would be bought out by the ever-expanding American Airlines in 1999 and ceased operations in August of that year.
American would, for a short time, use Reno Air’s former aircraft painted in a special flat color scheme (as opposed to polished metal). Cutbacks in the wake of the 9/11 attacks would result in American shuttering the hubs at RNO and SJC, as well as the sale of all aircraft acquired in the merger. Nothing is left of the former Reno Air.
Northwest opted for the P&W JT9D engines used by their 747s, rather than the usual GE CF-6s. The P&W required a different cowling, that is most noticable with the center engine. There, you can see a bulge on the straight-through inlet, only found with the JT9D.
Northwest Orient Airlines became Northwest Airlines after its merger with Republic Airlines on Oct. 1, 1986.
