After ground personnel went on strike Wednesday to demand higher wages, Berlin Airport canceled all of its flights.
The walkout impacted about 300 flights to and from the capital of Germany.
According to the Verdi labor union, its members want a monthly rise of 500 euros ($544).
Employers have reportedly offered employees a 2,000 euro one-time payment, according to the German news agency dpa.
The previous year saw the most significant yearly inflation in Germany in more than 70 years.
Full-year inflation reached 7.9% in 2022 as a result of significant rises in the price of food and energy.
