Easyjet seem to have snuck in an extra flight to Berlin from 17th May.
Was originally 8 weekly, with no flights on Tue/Sat but double daily Fri/Sun/Mon.
They certainly appear to have done some tweaking in August compared to what I'd noted for June.
I can still only see 8 for SXF with only 1 flight Monday, but up from 6 last summer ?
AMS in Aug is 21 per week v 22 in June but a significant increase from 2015.
BFS drops 1 a week in August to 16 x weekly and PMI surprisingly perhaps drops to 5 x weekly from daily.
PRG is 5 x weekly in June but 4 in Aug.
On the other hand, GVA now shows double daily, up 1 from 13 x weekly.
and Basle daily in August, up from 5 x weekly.
Hasten to add I've not checked all destinations.
