German trade union Verdi announced a warning strike of ground personnel at Berlin's Tegel airport on Friday that started at 0500 GMT and was due to end at 0830 GMT.
A warning strike usually occurs when negotiations are ongoing, compared with a strike when talks have failed or are at a dead end.
The union has called for a wage increase of 4 percent for the approximate 1,500 staff.
