NEW YORK (AP) _ Former secretary of state Alexander Haig and former House Speaker Tip O'Neill don't usually see eye to eye, but they do agree on the benefits of flying the Trump Shuttle, according to a new advertising campaign.

Haig and O'Neill are one of several odd couples seated together in the television and newspaper ads. Others include author Norman Mailer with boxing promoter Don King, and sex counselor Dr. Ruth Westheimer with fashion model Carol Alt.

''The Trump Shuttle: the Ultimate Connection'' is the theme of the campaign, which starts Wednesday in the shuttle cities of New York, Boston and Washington.

''Each commercial focuses on an ironic juxtaposition,'' said Mark Messing, senior vice president at Scali, McCabe, Sloves, the ad agency responsible for the campaign. ''We chose personalities with little in common and asked them to engage in unscripted conversation.

''In most areas - ideology, culture, politics, style - they disagreed about everything, with the one common ground being their choice of the Trump Shuttle.''

Trump Shuttle, which developer Donald Trump bought from strikebound Eastern Airlines in early June, has been in a fierce battle for market share with the rival shuttle run by Pan Am Corp. The start of the new Trump advertising campaign corresponds with the customary fall increase in shuttle traffic.
