Luxe line Regent's new perk: Business class flights for all

Regent Seven Seas Cruises just fired another salvo in the can-you-top-this battle for wealthy travelers.

The luxury line Wednesday said it would become the first cruise operator to include business class flights to its ships in the fare for all customers.

The offer applies to all European, Asian and South American voyages where a customer would need to travel on an intercontinental flight in order to reach the ship or to return home.

Regent said the included business class flights would be available to and from 26 U.S. and Canadian gateway cities.

Even passengers in the lowest categories of cabins will be eligible for the included flights.

Regent bills itself as the most inclusive cruise line. It already includes shore excursions, fine wine and spirits, unlimited Internet access, prepaid gratuities, ground transfers and pre-cruise hotel stays in its fare.
