United adding new routes in push for high-fare passengers

United adding new routes to Europe with a Boeing jet that will have fewer seats but more in business class

United said Thursday that it will add European flights from Newark, New Jersey; Chicago; Denver and San Francisco.

It's adding destinations such as Nice, France, and Palermo, Italy, to woo premium leisure travelers. And it's adding flights to places it already flies, like London, that appeal to business travelers.

Many of the flights will use a version of Boeing's 767 jet that United is configuring with fewer seats than planes it is replacing — but crucially, with more business-class seats that generate much higher fares.
