So Ryanair for Summer 2019 looks like this.
Faro is 2 weekly Monday and Friday the same as this year.
Monday FAO-CWL 08.45-11.25 CWL-FAO 11.50-14.30
Friday FAO-CWL 16.20-19.00 CWL-FAO 19.25-22.05
Tenerife South is 1 weekly Thursday the same as this year.
TFS-CWL 14.20-18.15 CWL-TFS 18.40-22.45
Malta NEW is 2 weekly Wednesday and Sunday
MLA-CWL 07.00-09.25 CWL-MLA 09.50-14.15
Barcelona NEW is 2 weekly Tuesdays and Saturdays
Tuesday BCN-CWL 08.25-09.30 CWL-BCN 09.55-13.00
Saturdays BCN-CWL 07.40-08.45 CWL-BCN 09.10-12.15
That gives Cardiff 7 weekly flights from Ryanair +4 on 2018 and a Ryanair movement on every day of the week.
