Planning to travel next Sunday night or Monday and looking for updated info? (Note: travel/transportation disruptions are expected as early as 19:00h on Sunday evening.)
Here are my best bets:
Brussels Airlines on Twitter @Flyingbrussels
Brussels Airport on Twitter @Brusselsairport
Eurostar on Twitter @Eurostar
For most of the above, Twitter seems to be more regularly updated than the website, and some of them (particularly @Flyingbrussels) are pretty good at replying to any questions you send directly to them (which is not the case with their phone customer service).
So, if you’re planning to travel… Good luck!
