Further to the discussions regarding missing routes, this may clarify things for whoever is supposed to be filling in the gaps:
Currently MyFlights is showing 200+/- flights of which around 70 are ADS-B. (That might sound low, but it's about average in my experience. The most I've ever seen was 102 out of 250)
Of the ADS-B flights up to 50% can be European LoCost carriers and this is the main problem area. The following airlines have little or no route information:
TOM/WZZ/EZY/RYR/TCX/EXS/BMI/MON
Whilst I appreciate that details for these operators may prove difficult to track down, they form such a major part of MyFlights here in the UK that route data for them is essential.
It's perhaps worth adding that we're by no means 100% on some of the bigger operators such as KLM and DLH either. Summer schedules?
Hope this helps.
