Easyjet S19 doesn’t appear have to thrown out any surprises.
BCN goes daily from June, ATH from 4 to 5 weekly, LIS from 3 to 4 weekly, PRG from 6 to 7 weekly (PRG was 6 weekly this summer, then 9 weekly over winter so increase is based on S18 to S19).
One point to note is that SXF isn’t on sale for the Summer but I have heard that the route will operate to TXL instead, and thus will be announced as a ‘new route’ in November/December.
FAO seems to go from 4 weekly to 3 weekly and BFS seems to be just 2 daily most days, which is unlikely to stay that way.
given there will be 3 more aircraft to make 17 based, we can be sure there will be a lot of other changes to come.
