All-business class airline OpenSkies is offering a guarantee to customers that they will enjoy their flight — and a full refund if they don’t.

The airline announced its new “Love Everything or Pay Nothing” guarantee September 8, saying that the offer was unprecedented in the airline sector.

It says that the deal was prompted by a survey of passengers that revealed 96.85 percent of its passengers would recommend the airline.

British Airways is going to buy the French all-business airline l’Avion for 54 million pounds ($107 million) as it steps up efforts to take advantage of the recent liberalization of transatlantic travel.

The privately owned airline flies two Boeing 757 aircraft with 90 seats each between Paris and New York. L’Avion has flown 65,000 passengers since its January 2007 launch.

The deal, which includes £26m of net cash on L’Avion’s balance sheet, will allow OpenSkies to raise its Paris Orly-New York flights to three per day. Both carriers use reconfigured Boeing 757 aircraft.
