Believe me, I am all for the truth.
The 29th October 2019 was also after daylight savings time ended, and under the winter schedule. Today, the first day of the winter schedule this year, there are approx. 560 flights, and that includes Wizz Air Abu Dhabi. From your own link, you can easily see that the only week in which Wizz was flying significantly more than 2019 was the last one, which is due to the delay in changing to the winter schedule as daylight savings time ends.
