Looking at the reasons for my delays and on many of the routes that have been delayed by about 20 minutes say 'Force majeure' and having looked at the news there is no reason for this to happen. Can anyone help?
Force majure is directly related to the events page on the game world. I don't have access to the game world, but if you look in the news section, you'll see something like "volcanic eruption in <somewhere>, flights expected to be hosed for <time period>". So, for that time period, you're hosed, and then as normal operations resume, force majure will drift off to 0%.
