Air Berlin (1991) (Berlin Tegel) CEO Hartmut Mehdorn has called the new plan to only open Berlin Brandenburg on March 17, 2013 "unacceptable" voicing strong concerns that Berlin Tegel will be able to handle all of the additional traffic and connecting passengers by both Air Berlin (1991) (Berlin Tegel) and Lufthansa (LH, Frankfurt International). A lot of additional services were scheduled by both carriers based on the planned opening date of June 3, 2012 and Air Berlin had started to sell much more connections via the new airport than it had offered at Tegel before.
