Skyjacked (1972) - James Brolin holds a plane full of Walter Pidgeon (as an old coot who goes "boating" with the POTUS), NFL legend/needlepointist/actor/Rev. Rosey Grier, Yvette Mimieux and Susan Dey hostage and only captain Chuck Heston can stop him. Rather slipshod, TV movie-alike semi-disaster plodder, a sort of bastard cousin of the Airport series - but John Guillermin adds some touches e.g. Brolin constantly having fantasies of being a hero to the Soviets, hallucinating medal ceremonies. The end - set in a convincingly freezing-looking Soviet wasteland (supposedly Moscow Airport, actually Mojave, convincingly doubled via tons of realistically sludgy fake snow).
