airberlin is a oneworld airline, partner of American and British Airways, that’s largely controlled by UAE-based Etihad. They have a great business class product for long haul travel, and they do not add fuel surcharges to their fares. That means when redeeming miles, even British Airways miles for travel across the Atlantic, there are no fuel surcharges.
airberlin is increasing its US flights by 40% going from 55 to 78 weekly flights with fantastic award space in business class for the new flights.
