Mr87 --
Any reassurance you get from here isn’t really worth the screen space it’s typed on, not really.
Having said that, I don’t have any concerns about my own flights (LH) during that period – make of that what you will.
I guess my point is that us in here have a view but it is not really worth much more than that however informed that view may or may not be.
I hate to repeat what’s often shouted out in times of disruption but, “speak to your airline” and gather reassurance from them.
Whatever happens I wish you good luck matey, flights aint cheap and none of us book them just for the joy of it, we all have to get somewhere after all, it’s no small thing when it goes wrong.
