They have monthly updates of first visits and some other useful information about FRA and other airports, many links etc..
All the daily regs will be hard to get, I could imagine, Niether Fraport no ATC would give access to their systems. Many years ago, Fraport had "semi-public" PC terminals with flight arrivals and departure informaiton, not for the general public but for those who could read the abbreviations it was quite helpful information when you went out to meet someone. Knowing the arrival gate meant knowing which door you had to go to.
