Frankfurt, London and Roma will be staffed during this event, and much of the en-route ATC should be too. if you're planning on attending this event drop a message here and maybe a few of you can get together?

Note: Intercity flights don't need to be booked, but you may find that prefiling your flightplan expediates obtaining departure clearance. Obviously if a few people turn up you can't all share the same flight number. We recommend you substitute the last part of the flight number for a letter (i.e. if ICX110 is already online, login as ICX11A)
I'll be there!
