Lufthansa has cancelled nearly all of its domestic and European flights today due to strike action.
Flights to and from London, Manchester, Birmingham, Newcastle, Glasgow, Dublin, Aberdeen and Edinburgh will be hit.
A few short-haul flights will operate, such as in Berlin where the industrial action should end by 2:30pm.
The strike had a major knock-on effect on long-haul flights yesterday.
Only six of the scheduled 50 long-haul flights operated in Frankfurt and only three of the 17 planned flights in Munich. But in Dusseldorf all three long-haul flights operated as planned.
Flights operated by Germanwings will not be affected.
The strikes have been called by the union ver.di over wages and working conditions.
Lufthansa is reported to have rejected union demands for a 5.2% wage increase over the next 12 months and strikers are also looking for guarantees over job cuts.
Talks between the airline and the union broke down last week.
"It’s completely out of proportion," a Lufthansa spokesman was quoted as saying by the Reuters news agency,
"Especially given that four further dates for pay talks had already been agreed upon."
Lufthansa said it regrets any inconvenience to passengers and would "do its utmost to minimize impacts".
