In parallel running of Radarbox and FD7.5 today, out of 354 FlightIDs, FD7.5 returned 84 different or additional routes:
That's 24% which is high but as we mentioned before it's difficult to draw any conclusions without thorough checking.
On which point the very limited time I spent this afternoon working on EGNX flights was sufficient to convince me that I can crack the majority of lo-cost flights, esp. Ryanair & BMI in and out of EMA.
It's a bit laborious and time consuming but a bit of experience on my part will speed things up. Anyone who can monitor a local airport that offers an accurate flight info service can make a big impact on these missing routes.
An encouraging day one way and another.
