Verdi negotiator threatens longer strikes. Lufthansa canceled up to 90 percent of its 600 planned take-offs and landings due to the 27-hour warning strike.

More than 100,000 passengers had to reschedule. Verdi is demanding 12.5 percent more salary, but at least 500 euros per month for a term of twelve months. The airline points to past wage increases and has offered 13 percent more money and an inflation compensation bonus for a period of three years.
